Do you often run into this frustrating situation: a colleague sends you a bunch of Excel files, but the system only accepts CSV format; you want to import sales data into a database, but you get stuck at the format conversion step; or you just want to simply share spreadsheet data, but the recipient doesn't have Office installed and can't open them? Every time, you have to open the spreadsheet, click Save As, and manually change the file names one by one—not only is it a hassle, but it’s also error-prone. Don't worry, today I'm going to introduce you to some powerful conversion tools that will let you completely say goodbye to this kind of repetitive, mechanical work and experience what it feels like to batch convert Excel files to CSV format at lightning speed.
Why Convert Excel to CSV Format?
1. Program Development and Data Analysis: When using Python or R for data analysis, or importing data into MySQL or SQLite databases, CSV format is almost always required.
2. Cross-System Data Exchange: When transitioning between old and new company systems or transferring data between different software, CSV is the recognized "universal language," minimizing compatibility issues to the greatest extent.
3. Email Sending and Archiving: Excel files are often several megabytes, but after converting to CSV, they might only be tens of kilobytes, making them fast to send and saving significant space when archiving.
4. Simplified Data View: Sometimes we only need the numbers and text within a table, not complex formulas and formatting. Converting to CSV makes the data "cleaner."

Method 1: Use HeSoft Doc Batch Tool to Convert Excel to CSV
Recommendation Index: ★★★★★
Advantages:
1. Truly lossless batch conversion. Say goodbye to repetitive single-file operations. Whether a dozen or a thousand files, drag and drop them all at once or select a folder, boosting efficiency by hundreds of times.
2. Precise format preservation. The conversion engine is deeply optimized to ensure accurate data migration. Special characters and Chinese content are perfectly preserved, achieving a "flawless" data conversion.
3. Local offline processing. All operations are completed locally on the computer, and data never touches the network. This eliminates the risk of data leakage and provides protection for data information.
4. Minimalist three-step operation. The process is clear and intuitive, with no complex options, allowing any user to get started immediately.
Disadvantages:
【 HeSoft Doc Batch Tool 】can only be used locally on a computer.
Operating Steps:
1. Open 【 HeSoft Doc Batch Tool 】, select 【Excel Tools】 on the left, then choose 【Excel to Csv】 on the right.
2. Click 【Add Files】 in the upper right corner, or drag and drop the files to be converted into the designated area to complete file import.
3. Click 【Next】, and the tool will start batch converting Excel to CSV. A notification will appear upon completion.
Method 2: Use Excel's Built-in "Save As" Feature to Convert xlsx to CSV
Recommendation Index: ★★★☆☆
Advantages: The most orthodox and direct method, completely free, requiring no additional software. The compatibility of the converted file is guaranteed, making it the preferred choice for processing a single file.
Disadvantages: The biggest drawback is the inability to batch process. Each file requires the repetitive cycle of "open-save as-close," resulting in extremely low efficiency. Moreover, for files containing multiple worksheets, only the currently active worksheet can be saved.
Operating Steps:
1. Open the .xlsx or .xls file you need to convert using Microsoft Excel.
2. Click the "File" menu in the upper left corner, then select the "Save As" option from the drop-down list.
3. In the save dialog that pops up, click the drop-down menu next to "Save as type".
4. Find and select the "CSV (Comma delimited) (*.csv)" or "CSV UTF-8" format from the long list.
5. Choose a save location for the file, optionally modify the file name, and then click the "Save" button.
6. The system might pop up a prompt telling you that certain features might be lost; click "Yes" to confirm.
Method 3: Use an Online Conversion Website to Convert Excel to CSV
Recommendation Index: ★★★☆☆
Advantages: No software installation required; works right in the browser. Especially suitable for temporarily processing one or two files on someone else's computer. Usually supports multiple format interchanges, which is quite convenient.
Disadvantages: Privacy and security are the biggest concerns. You need to upload Excel files that may contain trade secrets or personal sensitive information to unfamiliar servers. Users often face file size and quantity limits, and conversion speed depends on internet speed.
Operating Steps:
1. Search for "Excel to CSV online" in your browser and open a website like Zamzar.
2. Click the "Choose File" or "Add File" button to select the Excel file you want to convert from your computer.
3. In the "Convert to" or output format options, select the "CSV" format.
4. Some websites may ask you to enter an email address to receive the download link after conversion is complete.
5. Click the "Convert" or "Start" button and wait for the file to upload and process.
6. Once processing is done, click the download link to save the CSV file to your local machine.
Method 4: Use WPS Office to Convert Excel to CSV
Recommendation Index: ★★★☆☆
Advantages: WPS is fully compatible with Microsoft Office formats, and its "Save As" function is almost identical to MS Office's.
Disadvantages: Like Microsoft Excel, it can only process single files and cannot batch convert. The software interface has relatively many ads, and there may be occasional subtle differences in conversion results when handling complex Excel formatting.
Operating Steps:
1. Open your Excel file using WPS Spreadsheets.
2. Click the "WPS Spreadsheets" menu in the upper left corner, select "File" -> "Save As".
3. In the save type list, find and select the "CSV (Comma delimited) (*.csv)" format.
4. Choose the save path and click "Save".
5. You will similarly receive a prompt about possible format loss; confirm it.
Method 5: Use Google Sheets to Convert xlsx to CSV
Recommendation Index: ★★☆☆☆
Advantages: A perfect cross-platform solution, usable as long as you have internet and a browser. Collaborative editing features are powerful, and it's very convenient to download as CSV after importing an Excel file.
Disadvantages: Requires an internet connection and a Google account. Uploading files to Google's cloud raises privacy concerns. For large files, the wait time for uploading and processing can be long.
Operating Steps:
1. Log in to your Google Drive.
2. Click "New" -> "File upload" to upload your local Excel file to the drive.
3. After the upload completes, right-click the file and select "Open with Google Sheets".
4. Once the file is open in Google Sheets, click "File" -> "Download" -> "Comma Separated Values (.csv)".
5. The browser will automatically start downloading the CSV file to your default download folder.
Method 6: Use the Open-Source Office Suite LibreOffice to Convert Excel to CSV
Recommendation Index: ★★☆☆☆
Advantages: A completely free, powerful, open-source office software that can replace Microsoft Office. Its Calc component can open Excel files and save them as CSV, and it supports command-line batch operations.
Disadvantages: The software is quite large, and the interface and operational logic differ from MS Office, requiring adaptation. Although it supports command-line batch processing, the command parameters are complex and difficult for ordinary users to master.
Operating Steps:
1. Install and launch LibreOffice, and open its Calc component (equivalent to Excel).
2. Click "File" -> "Open" to import your Excel file.
3. Click "File" -> "Save As" again.
4. In the file type list, select "Text CSV (.csv)".
5. Click save, and a dialog box will pop up letting you choose the field delimiter (choose comma) and character set (choose UTF-8).
6. Confirm to save.
Method 7: Use Professional Format Factory Software to Convert Excel to CSV
Recommendation Index: ★★☆☆☆
Advantages: A well-known "universal" format conversion tool supporting various formats like video, audio, images, and documents. Users familiar with this software might try using it for document conversion.
Disadvantages: Its main business is not document processing. Support for needs like Excel to CSV conversion is an "ancillary feature," meaning stability and accuracy are not guaranteed, and errors are likely with complex tables.
Operating Steps:
1. Open the Format Factory software, and find the "Documents" -> "To CSV" category in the left function list.
2. After clicking, click "Add File" in the pop-up window.
3. Select your Excel file and add it to the list.
4. Click "OK" in the upper right corner to return to the main interface.
5. Select the task in the main interface task list and click the "Start" button.
6. After conversion is complete, view the file in the output folder.
Method 8: Use Apple Numbers (for macOS Users) to Turn Excel into CSV
Recommendation Index: ★★☆☆☆
Advantages: Mac users don't need additional installations. They can use the system's built-in Numbers app to open Excel files and export them in CSV format, offering a smooth experience.
Disadvantages: Limited to the macOS ecosystem. The exported CSV file might have minor differences in delimiters, encoding, and other details compared to the standards commonly used in Windows environments.
Operating Steps:
1. On your Mac, open your Excel file with Numbers.
2. Click "File" -> "Export To" -> "CSV..." in the menu bar.
3. In the pop-up options box, you can adjust text encoding and delimiter type.
4. Click "Next", and choose the save location and file name.
5. Click "Export" to finish.
