When a folder contains a large number of Excel spreadsheets that need to be uniformly converted to XLSB format, opening and saving each one individually is very inefficient. Using HeSoft Doc Batch Tool as an example, this article explains how to batch import xlsx files and complete the format conversion through the "Convert Excel to Xlsb" feature in Excel tools. The article includes explanations of effects before and after processing, detailed operation steps, and precautions, suitable for scenarios such as report archiving, data organization, and team file standardization.
Many office workers encounter this situation: after a project ends, they need to organize a batch of Excel reports, and the leader requires them to be uniformly saved as XLSB; or there are a large number of xlsx spreadsheets on the department's file server, and to unify the format, they need to be batch converted to binary workbooks. If you manually open each file and then execute "Save As", it is not only inefficient, but also difficult to ensure every file is processed correctly.
For a small number of files, manual conversion is not a major problem; but once the number of files increases, the repetitive labor becomes very obvious. Especially when file names are similar and folder levels are deep, manual processing can easily lead to problems like missed conversions, incorrect conversions, and chaotic save paths. This article introduces an approach more suitable for office scenarios: using HeSoft Doc Batch Tool to batch convert multiple Excel files to XLSB format.
HeSoft Doc Batch Tool is an office software whose interface provides tools for Word, Excel, PowerPoint, PDF, text, images, and more. Its core value is not to replace users in understanding document content, but to help users automate and batch-process a large number of repetitive file handling actions. For needs like "how to batch save multiple Excel files as XLSB", using a specialized batch conversion entry point is more stable and time-saving than manual operation.
Applicable Scenarios: Which Office Needs Are Suitable for Batch Save As XLSB
1. Centralized archiving of report files. Enterprise monthly reports, weekly reports, sales statistics, inventory counts, personnel lists, and other files are often uniformly archived after a period ends. Batch converting these Excel files to XLSB helps form a unified file format.
2. Historical xlsx files need format standardization. Some teams saved a large number of xlsx files in the early stages, and later, due to management requirements, need to uniformly change them to xlsb. If the quantity is large, saving each one individually wastes a lot of time.
3. File names need to remain consistent, only the format changes. In office collaboration, file names often carry important information, such as dates, departments, project numbers, or client names. If the main part of the file name changes during format conversion, it may affect subsequent retrieval. The ideal result of batch conversion is to keep the original name and only convert the extension to .xlsb.
4. The need to hand over repetitive operations to a tool. Batch converting Excel files does not require users to judge content one by one; the main tasks are selecting files, setting the output location, and executing the conversion. Such tasks are very suitable for completion by office batch processing software.
Result Preview: Batch Generate xlsb Files from xlsx Files
From the pre-processing screenshot, it can be seen that there are currently 3 Excel files: product_list.xlsx, team-participant-list.xlsx, and test.xlsx. They are all in xlsx format, which is a common type of Excel workbook file.

After processing is complete, the file extensions are uniformly changed to xlsb, corresponding to product_list.xlsb, team-participant-list.xlsb, and test.xlsb respectively. It can be seen that the main part of the file names remained unchanged; only the format changed. This indicates that after batch conversion, each spreadsheet can still be identified by its original file name, without disrupting the original file naming conventions.

For files that need to be delivered, archived, or uploaded to a system, this result is very intuitive: users only need to check whether the output files are all .xlsb to confirm if the format conversion meets the requirements.
Operation Steps: Batch Convert Excel Spreadsheets to XLSB
The explanation below follows the operational sequence shown in the software interface screenshots. To improve processing efficiency, it is recommended to first place the Excel files to be converted in the same folder, or at least confirm their locations for easy addition later.
Step One: Select Excel Tools on the Left
After opening HeSoft Doc Batch Tool , the left side shows the function category navigation. In the screenshot, "Excel Tools" is selected, indicating that Excel-related functions are currently being viewed. Since the processing objects are Excel spreadsheet files, you must first enter this category.
After entering Excel Tools, multiple conversion cards are displayed on the right. These cards cover different Excel output formats, including conversion to JPG images, Word, PDF, Csv, Xls, Xlsx, Xlsm, Xltx, Xltm, Txt, HTML web pages, Json, XML, and others. Users need to select the corresponding function based on the target format.

The target this time is XLSB, so select "Excel to Xlsb" in the interface. In the screenshot, this function card is located in the right area, indicated by a red arrow. After selecting this function, the software enters the dedicated Excel to XLSB batch processing page.
Step Two: Enter the "Excel to Xlsb" Page and Add Files
After entering the function page, the top shows the current processing function is "Excel to Xlsb". The interface uses a step-by-step workflow: "Select records to process," "Set save location," and "Start processing." This is important for batch conversion tasks because it allows users to confirm the files first, then decide the output location, and finally execute uniformly.
In Step 1, there is an Add File button and an Import Files from Folder button in the upper right corner. These suit different situations: if the files to be converted are scattered in different locations, you can select them one by one via Add File; if the files are already in the same folder, you can import from folder to improve selection efficiency.

The screenshot shows that 3 xlsx files have been added. The file list displays the sequence number, name, path, extension, creation time, modification time, and an operations column. Through this information, users can clearly know which files are about to be converted.
Step Three: Check the Record Count and Extension
After importing files, it is not recommended to proceed immediately; you should first check the list. The extension column in the screenshot shows xlsx, indicating the currently imported files are in Excel xlsx format. The summary area at the bottom shows a record count of 3, meaning the software will process 3 files.
If your actual number of files is larger, you can also quickly judge if any were missed by using the record count. For example, if you originally planned to convert 50 files, but the list only shows 45 records, you need to go back and check the file source or selection range. For batch file conversion, checking before processing often saves more time than rework after processing.
Additionally, the path column shows the file locations, for example, in the screenshot: D:\test\product_list.xlsx, D:\test\team-participant-list.xlsx, D:\test\test.xlsx. The path allows you to confirm if files from the correct folder were selected.
Step Four: Use Delete, Clear, Filter, or Sort to Assist in Organizing the List
After adding files, if you find a record does not need conversion, you can remove it using the delete icon in the operations column. The interface also has a Clear button at the top, suitable for starting over if a batch of files was selected incorrectly. The Filter and Sort buttons in the upper right of the list can help users view records more quickly when there are many files.
It should be noted that the advantage of batch processing lies in handling multiple files at once, but the prerequisite is an accurate list. Do not mix temporary files, test files, or spreadsheets that do not need conversion into the processing queue. Especially in team-shared folders with similar file names, pay extra attention to checking the path and extension.
Step Five: Click "Next" to Set the Save Location
After confirming the file list is correct, click Next at the bottom of the page. Step 2 in the interface workflow is "Set save location," indicating the software will require the user to specify where the converted files should be stored.
It is recommended to save the converted xlsb files to a separate directory, such as "XLSB Output," "Converted Files," or a project archive directory. This avoids mixing them with the original xlsx files and makes it easier to check the conversion results later. For important files, keeping both the original and converted versions is safer.
Step Six: Start Processing and Check the Output Results
After setting the save location, proceed to Step 3 "Start processing." The software will execute the batch conversion based on the file records in the list. After conversion is complete, go to the save location to view the output files and confirm if the extensions have changed to .xlsb.
Combined with the post-processing screenshot, the expected result is that each file generates a corresponding XLSB version, keeping the main part of the original file name unchanged. For example, product_list.xlsx converts to product_list.xlsb, team-participant-list.xlsx converts to team-participant-list.xlsb, and test.xlsx converts to test.xlsb.
Common Questions and Precautions
1. Must the files be placed in the same folder?
Not necessarily. The interface offers two methods: "Add File" and "Import Files from Folder." If files are scattered, you can add files; if they are concentrated in one folder, importing from a folder is more convenient.
2. Will the original files disappear after converting to XLSB?
The specifics depend on the save location setting and the actual processing results. To be safe, it is recommended to save the output files to an independent directory and keep the original xlsx files. This way, even if reprocessing is needed later, the original files are still available.
3. What is the purpose of the extension column in the list?
The extension column helps users confirm the type of files currently imported. In the screenshot, the extension is xlsx, meaning these files are xlsx workbooks. For batch conversion tasks, checking the extension can prevent irrelevant files from being mistakenly added to the queue.
4. How to reduce errors when the number of files is very large?
It is recommended to organize the folder first, then import; check the record count after importing; confirm the paths before processing; and select an independent save location for output. This can significantly reduce the probability of missed selections, incorrect selections, and being unable to find output files.
5. Is this method suitable for Excel files like xls, xlsm?
The screenshots in this article show batch conversion from xlsx files to xlsb. For other Excel formats, whether they are supported depends on the software's actual recognition and processing capabilities. The operational idea is similar: select the Excel to Xlsb function, add the Excel files to be processed, and follow the workflow.
Summary: Let Office Software Handle Batch Save As
The key to batch saving multiple Excel files as XLSB is not how to save a single file, but how to centralize the repetitive operations. HeSoft Doc Batch Tool , through its "Excel to Xlsb" function, organizes file selection, save location setting, and processing start into a clear workflow, suitable for handling large-scale xlsx spreadsheet conversion needs.
If you are facing a batch of Excel files that need a unified format, you can first enter Excel Tools, select "Excel to Xlsb," add files or import files from a folder, confirm the list, click Next, and complete the subsequent processing. Compared to manually saving each one individually, this method is more suitable for office batch processing, significantly saving time and reducing errors caused by repetitive operations.
