This article is aimed at office scenarios where a large number of Excel files need to be batch converted to CSV format, and introduces how to use HeSoft Doc Batch Tool to complete the conversion from xlsx to csv. The article combines before-and-after processing effect screenshots and software operation interfaces to explain the complete workflow from entering the Excel tool, selecting "Excel to Csv", importing multiple files, to setting the save location and starting the process, helping users reduce the repetitive operation of saving as CSV one by one, and improve the efficiency of data organization, system import, and cross-platform exchange.

In daily office work, many data are saved as Excel workbooks, such as sales data, project tasks, product lists, order records, meeting minutes, employee salaries, customer information, etc. Manually "saving a single file as CSV" is not complicated, but if you need to process dozens or even hundreds of Excel files at once, repeatedly opening, saving as, selecting the format, and confirming the save takes up a lot of time, and can easily affect subsequent work due to missed conversions, wrong path selection, or confusing file names.

This article solves the problem of "batch converting many Excel files to CSV format." Through office software like HeSoft Doc Batch Tool , you can import multiple xlsx files into the same task and then uniformly convert them to csv files. For users who need to perform database imports, business system uploads, data analysis, interface integration, or cross-platform sharing, the CSV format is more lightweight, universal, and easier to read programmatically. The following will explain how to complete batch Excel to CSV conversion based on actual operational steps, combined with screenshots.

Applicable Scenarios: Which situations are suitable for batch converting Excel to CSV

Excel files are suitable for editing, formatting, and formula calculations, while CSV files are more suitable for structured data exchange. The two have different positioning, so in many office workflows, it is often necessary to convert tabular data in Excel to CSV format. Especially when the number of files is large, using a batch processing tool is more stable and efficient than manual operation.

Common applicable scenarios include: first, business departments need to uniformly upload multiple Excel reports to ERP, CRM, financial systems, or e-commerce backends, and the target system only supports csv import; second, data analysts need to convert Excel files such as xlsx and xls to csv for convenient batch reading using Python, R, databases, or BI tools; third, roles in operations, sales, HR, etc., need to regularly organize a large number of spreadsheet files and deliver them to other systems or external partners; fourth, teams have fixed internal data templates and need to batch output CSV files weekly or monthly for archiving.

If the number of files is small, manual conversion can also be completed; but if the files are scattered in the same folder and the file names need to stay as consistent as possible, then using office software for batch conversion is more suitable. The core value of HeSoft Doc Batch Tool lies precisely in batch processing files, reducing repetitive labor, and improving office efficiency.

Result Preview: Before processing, there are multiple Excel files; after processing, they uniformly become CSV files

Before Processing: Files are still in Excel format

From the screenshot before processing, you can see multiple Excel files on the desktop or in a folder, with the file extension .xlsx. For example, Sales Data.xlsx, Project Tasks.xlsx, Product List.xlsx, Order Records.xlsx, Meeting Notes.xlsx, Feedback Survey.xlsx, Employee Salaries.xlsx, Customer Information.xlsx, etc. These files are all in Excel workbook format, suitable for opening and editing in Excel, but if you want to import them into some business systems or data processing scripts, they often need to be converted to CSV first.

After Processing: File extensions change to CSV

After the conversion is complete, the main body of the file names remains unchanged in the screenshot, but the extension has changed from .xlsx to .csv. For example, Sales Data.csv, Project Tasks.csv, Product List.csv, Order Records.csv, etc. This processing result is convenient for users to verify: file names are not renamed into unrecognizable numbers but retain their original business meaning, only changing the output format.

This method of "batch name retention and format conversion" is very important in multi-file delivery scenarios. Users can quickly confirm which Excel files have been successfully converted and can directly use the generated CSV files for subsequent import, sending, or archiving.

Operational Steps: Using HeSoft Doc Batch Tool to Batch Convert Excel to CSV

Step 1: Enter the Excel tools category and find "Excel to Csv"

After opening HeSoft Doc Batch Tool , you can see different types of tool categories in the left navigation bar, including Word tools, Excel tools, PowerPoint tools, PDF tools, text tools, image tools, etc. Since the current task is to convert Excel files to CSV, you need to first click "Excel Tools" on the left.

After entering the Excel tools page, multiple batch processing functions related to Excel will be displayed on the right. As seen in the screenshot, the page includes feature cards like "Excel to JPG Image," "Excel to Docx," "Excel to PDF," "Excel to XPS," etc. The one to select this time is "8. Excel to Csv," whose description is "Batch convert Excel files to Csv format." After clicking this function, you will enter the Excel to CSV processing flow.

The purpose of this step is to ensure the correct conversion task is selected. Because the office software might simultaneously offer various Excel format conversion capabilities, such as xlsx to xls, Excel to PDF, Excel to Image, etc. If the goal is to generate a csv file, you should select "Excel to Csv" to avoid entering other conversion tools.

Step 2: Add the Excel files to be converted

After entering the "Excel to Csv" page, the current function name is displayed at the top of the interface, and the processing flow is divided into three stages: Select records to process, Set save location, and Start processing. The current screenshot is at Step 1, "Select records to process." The top right of the page provides two entries: "Add files" and "Import files from folder."

If the number of Excel files to be converted is small and the files are scattered in different locations, you can click "Add files" to manually select the .xlsx files that need processing. If the files are all placed in the same folder, such as a project material folder, monthly report folder, or data-to-be-imported folder, you can use "Import files from folder" to import the Excel files from that folder into the list all at once. The red arrows in the screenshot point to these two import entries.

After the files are imported, the software will list the records pending processing in a table. In the screenshot, you can see the record list contains information such as sequence number, name, path, extension, creation time, modification time, and actions. The example shows 8 imported records, all with the extension xlsx, including Customer Information.xlsx, Employee Salaries.xlsx, Feedback Survey.xlsx, Meeting Notes.xlsx, Order Records.xlsx, Product List.xlsx, Project Tasks.xlsx, Sales Data.xlsx. Through this list, users can confirm before conversion whether the files have been fully imported and if the paths are correct.

Step 3: Check the file list and remove mistakenly selected records if necessary

Before batch conversion, it is recommended to check the file names and extensions in the list. Because CSV is a text format oriented towards data tables, accidentally selecting workbooks that don't need conversion might generate redundant files, causing interference to subsequent archiving or import.

From the screenshot, you can see that each record has an actions column on the right, displaying a delete icon. If a file is found that should not participate in this conversion, you can delete that record through the actions column. A "Clear" button is also provided at the top of the interface, suitable for use when the wrong folder has been imported or when preparing to re-select files. This avoids continuing to process on the wrong list basis.

The expected outcome of this step is that the pending list only retains the Excel files that truly need to be converted this time. For tasks with many files, it is recommended to pay special attention to the three pieces of information: file name, path, and extension, confirming they belong to the same batch of business data or pending materials.

Step 4: Click "Next" to enter the save location settings

After confirming the file list is correct, you can click the "Next" button at the bottom of the page. The bottom center of the screenshot shows the "Next" button. After clicking it, the process will enter Step 2 "Set save location."

The purpose of setting the save location is to specify where the converted CSV files should be output. A reasonable save location can reduce the risk of file chaos. In actual office work, it is recommended to set the output directory to a separate folder, such as "CSV Results," "Converted Files," or the project's corresponding output directory. This makes it easy to distinguish them from the original Excel files and facilitates subsequent unified uploading or packaging for sending.

Since the screenshot only shows up to the file import page, the specific controls on the save location page are not displayed, so the button names not appearing in the screenshot will not be described here. Users only need to follow the prompts on the software interface to complete the save location settings.

Step 5: Enter "Start Processing" and wait for the batch conversion to complete

After the save location is set, the process will enter Step 3 "Start processing." The progress bar at the top of the interface already indicates that this tool uses a step-by-step processing logic: first select records, then set the save location, and finally start processing. After entering the start processing phase, the user starts the task according to the page prompts and waits for the software to batch complete the Excel to CSV conversion.

After the conversion is complete, you can open the previously set output directory to verify. The expected result is that each imported Excel file will generate a corresponding .csv file, with the main body of the file name usually remaining consistent with the original file, and the extension changed to .csv. Combining with the post-processing result image, you can see that Sales Data.xlsx becomes Sales Data.csv, Project Tasks.xlsx becomes Project Tasks.csv, and other files are output following the same rule.

Frequently Asked Questions and Notes

1. Why doesn't a file look like its original table style after converting Excel to CSV?

CSV is essentially a comma-separated value text file, preserving tabular data rather than Excel's styling, colors, merged cells, formula formats, and other layout effects. Therefore, batch Excel to CSV conversion is more suitable for data exchange and system import, not as a delivery format that retains complex formatting. If you need to preserve the layout, consider other formats like Excel to PDF; if the goal is system reading, CSV is usually more appropriate.

2. Do I need to back up the original Excel files before batch conversion?

It is recommended to keep the original xlsx or xls files. The CSV is the output result, while the original Excel files remain an editable and traceable data source. Especially when involving important data like finance, HR, orders, and customer information, keeping the original files helps with subsequent verification.

3. When there are many files, should I choose "Add files" or "Import files from folder"?

If the number of files is small, using "Add files" is more flexible; if the files are concentrated in a single folder, using "Import files from folder" is more efficient. The example in the screenshot shows importing multiple xlsx files into the list for unified processing, suitable for batch tasks.

4. How do I verify the file names after conversion?

You can prioritize checking the main body of the file name and the extension. Before processing, it is Sales Data.xlsx; after processing, it is Sales Data.csv; before processing, it is Product List.xlsx; after processing, it is Product List.csv. As long as the main body of the file name is consistent and the extension becomes .csv, it is easy to confirm the conversion correspondence.

Summary: Using Batch Processing Tools to Reduce Repetitive 'Save As' Operations

Batch converting Excel files to CSV format is a very common office requirement in data organization, system import, and cross-platform collaboration. Manually opening each Excel file and saving it as CSV is not only time-consuming but also prone to omissions. With HeSoft Doc Batch Tool , users can select "Excel to Csv" in Excel tools, import multiple xlsx files via "Add files" or "Import files from folder," then set the save location according to the process and start processing.

For users who frequently handle reports, lists, orders, customer data, and employee data, this batch file conversion method can significantly reduce repetitive labor and improve the consistency of file processing. It is recommended that the next time you need to perform xlsx to csv, batch Excel to CSV, or multi-file format conversion, directly use the batch processing tool to complete the task, leaving time for more important data verification and business analysis.
