This article explains how to batch convert multiple Excel spreadsheet files to XLSB format, suitable for office scenarios where large amounts of xlsx, xls, and other spreadsheet data need to be organized. The article uses actual interface screenshots from HeSoft Doc Batch Tool to illustrate the complete process from selecting the Excel to Xlsb conversion function, importing files to be processed, to setting the save location and starting processing, helping users reduce repetitive "Save As" operations and improve file format unification and archiving efficiency.
In daily office work, Excel spreadsheets are often saved in various formats such as xlsx, xls, xlsm, etc., scattered across different folders. For data sheets, checklists, statistical reports, or business ledgers, if there are only one or two files, manually opening Excel and "Save As" XLSB one by one is acceptable. However, when dealing with dozens or even hundreds of Excel files, the repeated process of opening, saving, and closing becomes very time-consuming and can easily lead to issues like missing files, incorrect save paths, or misnamed files, affecting subsequent use.
XLSB is the Excel binary workbook format, commonly used for saving larger spreadsheet files. Many users convert multiple xlsx files to xlsb files when archiving, transferring, or unifying file formats. The problem this article addresses is: how to batch convert many Excel spreadsheet files to the XLSB format without opening each Excel file individually, but instead by using office software.
Below, with the help of screenshots, the method for batch converting Excel to XLSB in HeSoft Doc Batch Tool will be demonstrated. It is positioned as a tool for batch processing office files, with its core value lying in centralizing repetitive operations such as file conversion, organization, and renaming into a single workflow, helping users save a significant amount of time on mechanical tasks.
Applicable Scenarios: When is it suitable to batch convert Excel to XLSB
Batch converting Excel files to XLSB is not only suitable for technical personnel. Anyone who frequently works with spreadsheet files may encounter similar needs. The following scenarios are typical:
1. Archiving a large number of xlsx spreadsheets requiring a unified format. For example, monthly sales reports, inventory lists, product catalogs, personnel rosters, project data sheets, etc., submitted by different departments or colleagues, may not have a consistent file format. For subsequent archiving and management, they can be uniformly converted to the xlsb format.
2. Low efficiency of manual "Save As" when dealing with a large number of files. If a folder contains dozens of Excel documents, opening each one individually and using "Save As" to XLSB is not only time-consuming but also demands significant attention. Using a batch processing tool allows you to add multiple files at once and execute the conversion uniformly.
3. The need to retain original filenames with only the extension changed. As can be seen in the screenshots, files like product_list.xlsx, team-participant-list.xlsx, test.xlsx before processing become product_list.xlsb, team-participant-list.xlsb, test.xlsb after processing. The main body of the filename remains unchanged, with only the format changing. This is crucial for maintaining data structure and retrieval habits.
4. Reducing repetitive labor in office collaboration. Many document processing tasks in enterprises are not complex but highly repetitive. Delegating these operations to batch processing software allows employees to spend their time on data checking, analysis, and business judgment, rather than repeatedly clicking the save button.
Effect Preview: Before processing, multiple xlsx files; After processing, uniformly changed to xlsb
First, let's look at the file status before processing. The screenshot shows 3 Excel spreadsheet files named product_list.xlsx, team-participant-list.xlsx, and test.xlsx, all with the .xlsx extension. Such files typically display an Excel icon in Windows, and users can identify the current format directly from the filename.

After batch conversion is complete, the extensions of the same batch of files have changed to xlsb. The screenshot after processing shows that the main body of the filenames remains consistent: product_list.xlsb, team-participant-list.xlsb, test.xlsb. In other words, the focus of the conversion is to change the Excel workbook format to XLSB, rather than renaming the file content.

This processing outcome is very user-friendly for batch archiving: users do not need to re-establish file correspondences or manually check whether each file has been renamed correctly. As long as you confirm the converted extension is .xlsb, you can continue to use them for transfer, archiving, or subsequent office workflows.
Operation Steps: Using HeSoft Doc Batch Tool to batch convert to XLSB
The specific operations are described below according to the order of the screenshots. As this is a batch file processing task, it is recommended to first gather the Excel files you need to convert into one folder for easy one-time selection or import.
Step 1: Enter the Excel tools category, select "Excel to Xlsb"
After opening HeSoft Doc Batch Tool , you can see several office file processing categories in the left navigation bar, such as Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, Text Tools, Image Tools, etc. Since this task involves processing Excel spreadsheet files, you need to first enter the Excel Tools category.
On the Excel Tools page, the interface lists various Excel conversion functions in the form of feature cards, such as Excel to JPG Image, Excel to Word, Excel to PDF, Excel to Csv, Excel to Xlsx, Excel to Xlsm, etc. The function highlighted in the screenshot is "Excel to Xlsb", indicating that this entry is for batch converting Excel files to the Xlsb format.

The purpose of this step is to find the correct entry point for batch conversion. After selecting "Excel to Xlsb", the software will enter the processing workflow corresponding to this function. The expected result is to enter the file addition page, ready to select the Excel files that need conversion.
Step 2: Add the Excel files you need to convert
After entering the "Excel to Xlsb" function, the current function name can be seen at the top of the interface, and the page workflow is divided into 3 stages: Select records to process, Set save location, Start processing. The current screenshot shows Step 1, which is selecting the records to process.
Multiple operation buttons can be seen on the upper right, including Add File, Import Files from Folder, Clear, and More. If you only need to select a few specific Excel files, you can click "Add File"; if the files are already gathered in a folder, you can use "Import Files from Folder" for batch import. The red arrow in the screenshot points to "Add File", indicating that you can start adding the pending documents from here.

After files are added, the software displays each record in a list. The screenshot shows 3 files have been added, named product_list.xlsx, team-participant-list.xlsx, and test.xlsx. The list also displays information like path, extension, creation time, and modification time, making it convenient for users to confirm if the correct files have been selected before conversion.
The expected result of this step is: all Excel files to be converted appear in the list, and the summary area shows the number of records. The screenshot shows a summary record count of 3, indicating that 3 Excel files will be processed currently.
Step 3: Check the file list to confirm no files are missing or wrongly selected
The most feared issue with batch processing is not operational complexity, but selecting the wrong files. Before conversion, it is recommended to carefully check the "Name" and "Path" columns in the list. The Name is used to confirm the file itself is correct, and the Path is used to confirm the file source is correct. Path information is particularly important if files with the same name are distributed across different folders.
An operation column with a delete icon is visible on the right side of the list for each record. If you find a file that does not need conversion, you can remove it from the list. The interface also provides "Filter" and "Sort" buttons, allowing users to find files based on the list situation. No complex parameters need to be set here; just confirm that all files intended for conversion are in the list.
The purpose of this step is to perform a final confirmation before the official conversion, avoiding the conversion of irrelevant files to XLSB or the omission of key spreadsheets.
Step 4: Click "Next" to proceed to save location settings
After confirming the file list is correct, click Next at the bottom of the page. The screenshot shows the "Next" button at the bottom, and the top workflow indicates Step 2 as "Set Save Location". This shows the software uses a wizard-style flow, guiding users to select files first, then set the output location, and finally start processing.
When entering the save location settings, it is recommended to choose an easily identifiable output location based on your office habits. For example, you could save the converted XLSB files to a separate folder to distinguish them from the original xlsx files; or you could select a specified directory according to team archiving standards. The specific save location should be based on the options provided on the actual interface.
The expected outcome of this step is: to clearly define where the converted .xlsb files will be saved, avoiding the inability to find the files after processing is complete.
Step 5: Enter the start processing stage to complete the batch conversion
After the save location is set, proceed to Step 3, "Start Processing". This is the final stage clearly indicated in the interface workflow. After processing starts, the software will execute format conversion for each Excel file in the list one by one, converting the original xlsx files to xlsb files.
After processing is complete, you can go to the set save location to view the results. Referring back to the effect preview images, the converted file extensions should be .xlsb, and the main file names should remain consistent with the original files. For example, product_list.xlsx corresponds to product_list.xlsb, team-participant-list.xlsx corresponds to team-participant-list.xlsb, and test.xlsx corresponds to test.xlsb.
Frequently Asked Questions and Important Notes
1. What is the difference between XLSB and XLSX?
XLSX is the common Excel workbook format, while XLSB is the Excel binary workbook format. When users perform batch conversions, they are usually focused on unifying file formats, archival requirements, or specific workflow needs. The focus of this article is the batch conversion operation, not modifying spreadsheet content.
2. Will the filenames be changed after conversion?
As seen in the before and after processing screenshots, the main body of the converted filenames remains consistent, with only the extension changing from .xlsx to .xlsb. This method helps users continue to identify and find files based on the original filenames.
3. Can multiple Excel files be added at once?
Yes. The screenshot shows that 3 records were added at once, and the interface provides two entry options: "Add File" and "Import Files from Folder". For a large number of files, it is recommended to organize them into a single folder first before performing a batch import.
4. Is it necessary to back up the original files before conversion?
When batch processing files, it is recommended to keep the original xlsx files, especially when dealing with important data, financial statements, business ledgers, or customer information. Saving the converted xlsb files to a new location can mitigate the risk of operational errors.
5. Why should I check the list before starting the process?
Because a batch operation will affect multiple files at once. If files that do not need conversion are mixed into the list, you will have to re-filter them afterwards, which actually adds workload. By using the Name, Path, Extension columns, and the record count in the list, you can perform effective verification before conversion.
Summary: Using Batch Processing to Reduce Repetitive Labor in Excel Format Conversion
Batch converting Excel spreadsheet files to the XLSB format is essentially a highly repetitive, low-creativity office operation. While manual processing is feasible, efficiency drops significantly as the number of files increases, and problems like missed files or saving to the wrong location become more likely.
Through HeSoft Doc Batch Tool , you can select "Excel to Xlsb" under Excel Tools, add multiple xlsx files at once, set the save location after confirming the list, and start processing. The entire workflow is clear and suitable for users who need to unify spreadsheet formats, batch archive Excel files, or organize large amounts of report data.
If you currently have a batch of Excel files that need to be converted to XLSB, it is recommended to gather and organize the files first, then perform the batch conversion following the steps in this article. This can compress the work that originally required repeated opening and saving-as into a single batch process, significantly reducing repetitive labor.
