When faced with the task of converting a large number of Excel workbooks to the xlsb format, manually saving each one individually takes up a significant amount of time and is prone to issues such as missed conversions or incorrect conversions. Centered around scenarios involving batch processing of office files, this article introduces how to use HeSoft Doc Batch Tool to enter the Excel tool, select "Excel to Xlsb", batch add the spreadsheets to be processed, check the file list, set the save location, and complete the conversion. This is suitable for office needs like report archiving, data delivery, and file format standardization.
Many office workers encounter similar situations: a folder contains a batch of Excel workbooks, some are product lists, some are personnel rosters, and others are test data or business reports. Now, these files need to be uniformly converted to the XLSB format. However, if you rely on the Excel application to open and save each one individually, the process is not only cumbersome but also disrupts your normal workflow. The more files there are, the more likely problems such as missed conversions, duplicate saves, and saving to the wrong directory will occur.
This article focuses on the office scenario of "Batch converting a large number of Excel spreadsheets to XLSB files" and introduces a more suitable approach for batch processing: using the Excel conversion feature in HeSoft Doc Batch Tool to add multiple xlsx spreadsheets to a task list at once, then convert them all to xlsb files. This tool is a batch file processing product within office software. Its key value is not to replace the user's judgment on file content, but to help users reduce repetitive operations and streamline high-frequency actions like format conversion and file organization.
If you are searching for queries like "how to batch convert xlsx to xlsb," "batch save Excel files as xlsb," or "convert multiple Excel workbook formats," the following steps can be directly referenced.
Applicable Scenarios: Why Convert a Large Number of Excel Files to XLSB
There are many Excel file formats, with common ones including .xls, .xlsx, .xlsm, .xlsb, and others. Different formats suit different office needs. XLSB is the Excel Binary Workbook format, often used for scenarios requiring preservation of workbook data, formulas, and table structures. For some larger workbooks, the XLSB format might be more suitable for archiving or handling in terms of user experience; however, the final decision to adopt this format should be based on actual business requirements and the recipient's environment.
The need for batch converting to XLSB typically arises from the following types of tasks:
- Regular Report Archiving: Monthly, weekly, sales, and inventory reports, among other numerous files, need to be uniformly saved in a specified format.
- Cross-departmental File Delivery: Excel files submitted by different departments have inconsistent formats and need to be converted to a single format before delivery.
- File Server Organization: A large number of historical xlsx files exist on a shared drive and need to be changed to xlsb according to new archiving rules.
- Pre-data Processing Preparation: Before importing, summarizing, or subsequent analysis, standardize the workbook format first to reduce process differences.
- Reducing Manual 'Save As' Actions: Avoid repetitively performing the actions of opening, 'Save As', selecting the format, and closing the file over a long period.
These scenarios have one thing in common: converting a single file is not difficult; what truly consumes time is the repetitive processing of many files. Therefore, completing conversions centrally with office software that supports batch processing is more stable and efficient than a purely manual approach.
Preview of Results: Changes from XLSX Workbooks to XLSB Files
Before Processing: Multiple Excel Files Awaiting Conversion
The screenshot before processing shows 3 Excel files awaiting conversion: product_list.xlsx, team-participant-list.xlsx, and test.xlsx. These files all have Excel icons and the .xlsx extension, indicating they are currently in the common Excel workbook format.

In a real office environment, the 3 files in the screenshot can be considered a small batch example. If there are 30, or 300 similar files in a folder, the pressure of manual conversion multiplies. More importantly, manual operation lacks a unified task list, making it difficult to confirm immediately afterward which files have been processed and which have not. A batch conversion tool, however, first lists the files and then executes the conversion uniformly according to that list.
After Processing: Output File Extensions Changed to XLSB
In the screenshot after processing, the original 3 files have had corresponding .xlsb files generated: product_list.xlsb, team-participant-list.xlsb, and test.xlsb. Looking at the naming, the main file names remain consistent, and the extensions have completed the change.

This result is very suitable for batch verification. For example, the original file product_list.xlsx corresponds to the conversion result product_list.xlsb; team-participant-list.xlsx corresponds to team-participant-list.xlsb. Users do not need to reinterpret the file's meaning; they can judge the conversion result just by the name and extension. For folders intended for delivery or archiving, this clear correspondence can reduce subsequent communication costs.
Operation Steps: Batch Convert Excel Workbooks to XLSB
Step 1: Open the Software and Enter the Excel Tools Category
After launching HeSoft Doc Batch Tool , you can see clear functional categories on the left side of the software, including Home, Task Flow, All Tools, File Name, Folder Name, File Organization, Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, Text Tools, Image Tools, Video Tools, Audio Tools, etc. Since the target of this process is Excel spreadsheet files, you should enter Excel Tools.
After entering Excel Tools, the main area will display multiple Excel-related function cards. The screenshot shows many conversion functions, such as Excel to JPG Image, Excel to Word, Excel to PDF, Excel to Csv, Excel to Xls, Excel to Xlsx, Excel to Xlsm, Excel to Xlam, Excel to Txt, Excel to HTML Web Page, Excel to XML, etc. This shows that the software divides Excel file conversion tasks by the target format, and users only need to select the function matching their goal.

Because our goal this time is to generate XLSB files, we need to click number 18, Excel to Xlsb. The description below this card is "Batch convert Excel files to Xlsb format." This step is crucial, as Excel-related format names are similar. If you select "Excel to Xlsx" or "Excel to Xls," the final result will not be xlsb files.
Step 2: Enter the Conversion Page and Choose the Method to Add Files
After clicking "Excel to Xlsb," you will enter the task page for this function. The page title shows Excel to Xlsb, confirming you have entered the correct function. At the top of the interface, there is a Back to main panel button for returning to the function list; on the right side, there are operation entries like Add Files, Import files from a folder, Clear, and More.

If you only want to convert a few specific files, you can click Add Files. If your Excel spreadsheets are all concentrated in a specific folder, you can choose Import files from a folder, which better suits the habit of handling a large number of files. The red arrow in the screenshot points to "Add Files," indicating that the example uses this button to add files to the task list.
The purpose of this step is to hand over the Excel files to the software to form a processing list, rather than having users open files one by one. Once files are added to the list, you can uniformly set the save location and execute the conversion later.
Step 3: Review the Pending Records, Confirm File Names, Paths, and Extensions
After adding files, the list of files to be processed is displayed in the middle of the page. The list in the screenshot includes multiple columns of information: Number, Name, Path, Extension, Creation Time, Modification Time, Actions, etc. The current list has 3 records, with names product_list.xlsx, team-participant-list.xlsx, and test.xlsx; the Path shows they are located in the D:\test\ directory; the Extension column shows xlsx.
The role of this information is to help users complete verification before conversion. The biggest fear in batch processing is "selecting the wrong batch of files" or "missing a key file." Therefore, before proceeding to the next step, it is recommended to confirm item by item:
- Check the Name: Confirm the files are the Excel spreadsheets to be converted this time.
- Check the Path: Confirm the files come from the correct folder to avoid mixing in files from other projects.
- Check the Extension: Confirm the files are Excel workbooks, not other unrelated files.
- Check the Record Count: The bottom of the screenshot shows "Record Count: 3," which should match your expected number of files.
If you find incorrectly added files, you can remove them using the delete icon in the "Actions" column. If there are many files, the "Filter" and "Sort" buttons on the right side of the interface also help in viewing the list. After completing the review, the task list can serve as the basis for the subsequent batch conversion.
Step 4: Click Next and Set the Save Location for Conversion Results
After confirming the records to be processed are correct, click Next at the bottom of the page. The process bar on the interface shows: Step 1 is "Select records to process," Step 2 is "Set save location," and Step 3 is "Start processing." This shows the software adopts a step-by-step workflow, guiding users to select files first, then determine the output location, and finally execute the conversion.
It is recommended to set the save location according to your work habits. For batch converting Excel to XLSB, it is quite advisable to save the conversion results to a separate folder, for example, "xlsb output," "Converted Files," or a folder named by date. This separates the original xlsx files from the converted xlsb files, avoiding confusion in the same directory.
In a team collaboration scenario, you should also pay attention to whether the save location is easily accessible to other colleagues. For example, a department shared drive, project archive directory, or client delivery directory might have fixed conventions. Setting the output location clearly can reduce the extra step of moving files after the conversion is complete.
Step 5: Start Processing, Generate Batch XLSB Results
After setting the save location, enter Step 3 "Start processing." Once you execute processing according to the on-screen prompts, the software will convert the Excel files in the task list to the XLSB format in batch. After the conversion is complete, go to the save directory set in the previous step to view the output files.
According to the post-processing illustration, the conversion result should show the file extension changing from .xlsx to .xlsb, while the main file name remains corresponding. For instance, product_list.xlsx generates product_list.xlsb, test.xlsx generates test.xlsb. It is recommended to do a simple check after the conversion: First, whether the number of output files matches the record count in the task list; Second, whether the file names correspond; Third, spot-check one or two files to see if they open normally and meet business usage requirements.
Common Questions and Notes: What to Check Before and After Batch Conversion
1. Will Batch Conversion Affect the Original Files?
Judging from the process shown in the screenshots, the software guides users to set a save location and generate conversion results. To be safe, it is recommended to save the converted XLSB files to a new folder and keep the original xlsx files. This way, no matter if you need to reprocess later, the original materials will not be affected. For important data, backing up before any batch operation is always advised.
2. Why Pay Attention to the Extension?
The extension determines the file format. In this article's example, the extension before processing is .xlsx, and after processing it is .xlsb. Many users only look at the file icon, easily overlooking the format difference; but in scenarios like batch archiving, system uploading, and format verification, the extension is very important. After conversion, it is recommended to enable the display of file extensions to facilitate result confirmation.
3. How to Improve Accuracy When There Is a Very Large Number of Files?
You can first gather the Excel files to be converted into a dedicated folder in File Explorer, then batch-add them using "Import files from a folder." After importing, do not start processing immediately; instead, first check the record count, names, and paths. For hundreds of files, you can use the filtering and sorting functions in the list to assist with verification. The efficiency of batch processing comes from unified execution, but accuracy comes from the list check before conversion.
4. Can XLSB Files Be Opened by Everyone?
XLSB is a workbook format supported by Excel, but whether the recipient can open it smoothly still depends on their office software environment and version support. If sending files externally, it is recommended to confirm in advance whether the other party accepts the XLSB format. If it's only for internal company archiving or use within a unified environment, management is generally easier.
5. Is It Necessary to Check the Content After Conversion?
Yes. The completion of format conversion does not mean the end of the business check. Especially for workbooks containing formulas, charts, pivot tables, external links, or special formatting, it is recommended to at least spot-check key files to confirm that worksheets, data, and formatting meet expectations. Batch tools can save the time of conversion actions, but the correctness of the content should still be confirmed by the user according to business standards.
6. Can I Convert docx, pdf, and Other Files to XLSB Together?
This article demonstrates the Excel to XLSB conversion function, and the applicable objects should be Excel workbook files. Although you can also see categories like Word Tools, PDF Tools, and Image Tools in the interface, they correspond to other file processing tasks. If you need to handle files like doc, docx, or pdf, you should enter the corresponding tool category and select the matching function. Non-Excel files should not be mixed into the Excel to XLSB task list.
Summary: Batch Convert Excel Formats for More Efficient File Organization
For converting a large number of Excel spreadsheets to XLSB, the least suitable method is repetitive manual "Save As." It consumes a lot of time and makes it difficult to guarantee that every file is processed correctly. Through the "Excel to Xlsb" function of HeSoft Doc Batch Tool , users can first enter Excel Tools, select the corresponding conversion function, then add files in batch, verify records, set the save location, and finally generate XLSB files uniformly.
This approach is particularly suitable for report archiving, bulk delivery, historical file organization, and format standardization scenarios. It delegates repetitive operations to office software, allowing users to focus energy on file content review, data analysis, and business decisions. It is recommended to organize the source files and make backups before actual operation, and check the quantity and usability of the output files after conversion. As long as you follow the process in this article, you can more reliably complete the batch conversion of multiple Excel, xlsx workbooks to the xlsb format.
