When a folder contains a large number of Excel files such as xlsx and xls that need to be uniformly converted to xlsb format, opening and saving them one by one is not only time-consuming but also prone to missing files. This article uses HeSoft Doc Batch Tool as an example to demonstrate how to use the "Excel to Xlsb" feature in office software to batch import spreadsheet files, set the save location, and execute the conversion, helping users quickly complete Excel format unification, reduce repetitive operations, and improve file organization and archiving efficiency.
In daily office work, many teams save content such as sales details, product lists, registration lists, financial ledgers, and data reports as Excel spreadsheet files. As the number of files increases, a common requirement emerges: the need to uniformly convert a batch of .xlsx spreadsheets to .xlsb format for convenient future archiving, transfer, or use in specific business systems. If only one or two files are involved, manually opening Excel and using "Save As" for XLSB is manageable; however, if there are dozens or hundreds of Excel files in a folder, opening them one by one, selecting the format, saving, and closing becomes a repetitive task that is highly inefficient and prone to errors.
The problem this article aims to solve is clear: How to batch convert many Excel spreadsheet files to XLSB format. Using the office software " HeSoft Doc Batch Tool " as an example, the following content, combined with screenshots, will explain the complete workflow from selecting the function and adding Excel files to completing the conversion. This software is positioned as a batch file processing tool for office scenarios, and its core value lies in centrally handling repetitive tasks like file conversion, organization, and naming, thereby saving time and reducing the risk of missed processing.
Applicable Scenarios: When Do You Need to Batch Convert Excel to XLSB
XLSB is an Excel Binary Workbook format with the file extension .xlsb. Compared to the common .xlsx format, XLSB is often more suitable for storing and opening workbooks containing large amounts of data, formulas, or complex tables. Of course, actual file size and opening speed are affected by factors such as table content, formulas, images, and data volume, so it cannot be simply assumed that all files will become smaller or faster after conversion. However, in office environments requiring a unified file format, XLSB remains a very common target format.
The following scenarios are particularly suitable for using batch conversion:
- Project Data Archiving: After a project ends, various Excel reports submitted by multiple departments need to be uniformly converted to XLSB for centralized storage.
- Data Report Distribution: Operations, sales, or finance departments regularly generate a large number of .xlsx reports and wish to unify them into .xlsb before sending them to relevant personnel.
- Organizing Historical Files: Computers or shared drives contain years of accumulated xlsx and xls files that need to be converted to a specified format according to company standards.
- Preparation Before System Import: Some internal processes require a specific Excel format, and batch conversion can reduce manual preparation time.
- Reducing Repetitive Work: To avoid the mechanical process of "Open File—Save As—Select XLSB—Save" repeatedly.
If your requirement is to batch convert multiple Excel files to XLSB, rather than processing a single spreadsheet, using dedicated office batch processing software is more suitable. It can display the file list centrally, execute the conversion action uniformly, and allow you to check the pending files before conversion, avoiding missed or incorrect selections.
Effect Preview: Multiple XLSX Spreadsheets Before Processing, XLSB Files After
Before Processing: Common Excel Spreadsheet Files in the Folder
From the pre-processing screenshot, it can be seen that there are 3 Excel spreadsheet files in the current folder, named product_list.xlsx, team-participant-list.xlsx, and test.xlsx. The extensions of these files are all .xlsx, a common Excel workbook format.
If converted using the traditional method, these 3 files would need to be opened one by one and saved as XLSB individually. When the number of files is small, this is still manageable, but as the number increases, manual operation presents two problems: a significant increase in time consumption, and a high likelihood of missing a file due to interruptions. The value of a batch conversion tool lies in adding these files to a task list at once and then processing them uniformly.
After Processing: File Extensions Uniformly Converted to XLSB
The post-processing screenshot shows that the original 3 Excel files have become corresponding .xlsb files: product_list.xlsb, team-participant-list.xlsb, and test.xlsb. It can be seen that the main file names remain unchanged, with only the extension converted from xlsx to xlsb, making it easy for users to identify the correspondence between original and converted files.
This processing result is suitable for batch archiving and unified delivery. Especially when file naming is already standardized, retaining the original name after conversion can reduce subsequent verification costs. Users only need to confirm the output location and conversion results to quickly unify the formats of a batch of Excel files.
Operating Steps: Batch Convert Excel to XLSB Using HeSoft Doc Batch Tool
The actual operating procedure is explained below according to the screenshot order. The software name in the screenshots is HeSoft Doc Batch Tool , a batch processing software designed for office file scenarios. From the left-side navigation, it can be seen that the software categorizes different file tools, such as Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, Image Tools, etc. This article uses the Excel Tools within it.
Step 1: Enter Excel Tools, Select "Excel to Xlsb"
After opening the software, find and click Excel Tools in the left navigation bar. Once in the Excel Tools list, you can see multiple function cards related to Excel file conversion, 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 Xltx, etc.
In the current screenshot, you need to select the function card numbered 18: Excel to Xlsb. The description below this function card is "Batch convert Excel files to Xlsb format," which perfectly matches the goal of this article.
The purpose of this step is to enter the correct batch conversion task page. Many users may confuse formats like XLS, XLSX, XLSM, and XLSB when processing Excel files, so it is important to pay special attention to the target format when selecting a function. This tutorial aims to obtain .xlsb files, so "Excel to Xlsb" should be selected, not "Excel to Xlsx" or "Excel to Xls". After making the correct selection, the software will enter the corresponding task configuration interface.
Step 2: Add Excel Files to Convert
After entering the "Excel to Xlsb" page, you can see several operation buttons at the top, including Add Files, Import Files from Folder, Clear, and More. The middle of the page shows the current task flow: Step 1 is "Select Records to Process," Step 2 is "Set Save Location," and Step 3 is "Start Processing."
If you only need to select a few specific files, you can click Add Files to include the Excel spreadsheets to be converted in the list. If your Excel files are all in the same folder, you can use Import Files from Folder, which is more suitable for batch scenarios. The red arrow in the screenshot points to the "Add Files" button, indicating that the current example uses the add file method.
After files are added, the list displays the records to be processed. The screenshot shows that 3 files have been added: product_list.xlsx, team-participant-list.xlsx, and test.xlsx. The list also shows information such as file path, extension, creation time, and modification time. This information allows users to check whether the correct files were selected before conversion. For example, the path column shows the files are located in the D:\test\ directory, and the extension column shows xlsx, confirming that these files are indeed the Excel spreadsheets to be converted.
The expected result of this step is to add all the Excel files to be converted to the task list and confirm the record count is correct. The screenshot bottom shows "Record Count: 3," indicating that 3 files will be processed. If the record count doesn't match expectations, you should add missing records or delete incorrect ones before proceeding.
Step 3: Check Pending Files, Remove Errors if Necessary
Before batch processing, checking the list is very important, because once the subsequent processing flow begins, the software will uniformly execute the conversion on all records in the list. The "Actions" column in the screenshot provides a delete icon, which users can use to remove files they do not wish to process. The right side of the interface also shows "Filter" and "Sort" buttons, which are convenient for filtering or adjusting the viewing order when there are many files.
The operational purpose of this step is to avoid converting irrelevant Excel files together. For example, if you only want to convert reports for a specific project but accidentally selected spreadsheets from another department, you can delete that record before starting the process. Although batch processing is efficient, having an accurate task list is a prerequisite. Therefore, it is recommended to check at least three items before clicking the next step: whether the file names are correct, whether the extensions are those of the Excel files to be converted, and whether the paths point to the correct folder.
Step 4: Click "Next" and Set the Save Location
After confirming the file list is correct, click Next at the bottom of the page. In the interface flow prompt, Step 2 is "Set Save Location," meaning the software will guide the user to specify where the converted XLSB files should be saved. For batch conversion tasks, the save location is particularly critical because it relates to whether the original files can be easily distinguished and whether the conversion results are easy to find.
It is recommended to save the output files to a separate folder, such as "XLSB Conversion Results" or "Converted_xlsb." This has two advantages: first, it prevents the converted files from mixing with the original xlsx files; second, it facilitates subsequent unified checking, packaging, or uploading. If the company has uniform requirements for file archiving paths, you can also choose the save location according to internal specifications.
Since the screenshot clearly shows the flow includes "Set Save Location" but does not display the specific save interface, more button names not shown in the screenshot will not be elaborated here. In practice, just follow the software page prompts to complete the save location setting.
Step 5: Start Processing and View Conversion Results
After completing the save location setting, proceed to Step 3 "Start Processing" according to the flow. Once the task configuration is confirmed, execute the processing, and the software will batch convert the Excel files in the list to XLSB format. After the conversion is complete, check the result files in the set save location, and you will see the new files with the .xlsb extension.
From the effect preview, it can be seen that the processed file names correspond one-to-one with the original files, with the extension changing from .xlsx to .xlsb. This result is very user-friendly for subsequent verification: users can quickly confirm whether each source file has been successfully converted based on the file name. If a large number of files were processed, it is recommended to conduct spot checks based on file quantity, names, and necessary content to ensure the conversion results meet expectations.
FAQ and Notes
1. Do I need to back up the original Excel files before conversion?
It is recommended to keep a backup of the original files. Although the goal of batch conversion is to generate XLSB files, backing up is a safe practice in any batch file processing scenario. Especially when dealing with important files like financial reports, customer data, or project ledgers, it is best to store the original xlsx files separately and save the conversion results in another folder. This way, if recovery or re-conversion is needed later, the source files can be quickly found.
2. When dealing with many files, should I use "Add Files" or "Import Files from Folder"?
If the files are scattered in multiple locations, or you only need to process a few specific files, you can use "Add Files." If all the Excel files are concentrated in the same folder, using "Import Files from Folder" is more suitable for batch operations. Both entry points can be seen in the screenshots, and users can choose based on their actual file organization.
3. Will the file names change after conversion?
Based on the processing results in this article's example, the converted files retain the original file's main name, with only the extension changing to .xlsb. For example, product_list.xlsx becomes product_list.xlsb after conversion. This makes it easy to identify the file source and correspond it with the original file. However, in actual use, it is still recommended to check the output folder after conversion to confirm that the naming and quantity meet expectations.
4. Is the XLSB format suitable for all Excel files?
XLSB is one of the workbook formats supported by Excel, but whether it is suitable depends on your business needs. If it's just for circulating common spreadsheets, xlsx is common enough; if it's for large-volume workbooks, needing a unified archive format, or if an internal system requires xlsb, then converting to XLSB is appropriate. Before conversion, one should also consider whether the recipient's software environment supports opening XLSB files.
5. How to reduce errors during batch conversion?
It is recommended to follow three principles: organize source files first, then add to the task list, and finally check the output results. Organizing source files can reduce incorrect selections; checking the task list prevents missed processing; checking output results verifies whether the conversion is complete. For batch tasks with a large number of files, it is not recommended to organize and convert simultaneously. Instead, collect all pending files into a fixed folder first, then operate uniformly.
Summary: Let Batch Processing Tools Handle the Repetitive Excel "Save As" Tasks
Batch converting Excel spreadsheets to XLSB is essentially a typical office efficiency problem. The difficulty of manual conversion lies not in technical complexity but in the high number of repetitions, ease of interruption, and tendency to miss processing. Using the "Excel to Xlsb" function in HeSoft Doc Batch Tool , you can add multiple xlsx files to a processing list at once, check the records, set a unified save location, and then batch generate xlsb files.
For office personnel who frequently handle reports, lists, ledgers, and data files, this type of batch file conversion tool can effectively reduce mechanical operations, leaving more time for crucial data verification, analysis, and delivery work. If you have a batch of Excel files that need converting to XLSB, it is recommended to first gather the files into one folder, then follow the steps in this article to enter Excel Tools, select "Excel to Xlsb," add the files, and execute batch processing. This allows for a faster format unification and makes the file organization process more standardized.
