About the Excel to CSV Converter
Need to turn a XLSX file into CSV? This free converter changes XLSX spreadsheets into CSV in a few seconds, right in your browser. People usually convert because XLSX needs a spreadsheet app and is awkward to load into databases or code, while CSV gives you a CSV ready to import anywhere. CSV files open in Excel, Google Sheets, Notepad, MySQL, pandas and every CRM.
Spreadsheets are read and written with SheetJS, the open-source spreadsheet engine used by thousands of data apps, so every sheet, row and value is handled accurately. Because everything happens on your own device, your spreadsheets are never uploaded, stored or seen by anyone else, which makes it safe for customer lists, salary sheets, GST data and API exports.
What to expect: every sheet in the workbook is converted; formulas are exported as their calculated values, while text such as PIN codes and phone numbers with leading zeros stays intact.
How to use the Excel to CSV Converter
- Click "Choose files" or drag your XLSX spreadsheets onto the box. You can add several at once.
- Choose whether to convert all sheets or only the first one.
- Press "Convert to CSV". The conversion runs on your device and shows its progress.
- Download each CSV file, or use "Download all (ZIP)" when you converted several.
- Open the result in Excel or Google Sheets to check it; your original XLSX is never changed.
Tips & benchmarks
- CSV holds one table without formatting; with several sheets you get one CSV per sheet, bundled in a ZIP.
- To open the file in Excel with Hindi or ₹ characters intact, use Data → From Text/CSV and choose UTF-8; the file includes a UTF-8 marker for this.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the CSV to a website or government portal.

Click "Choose files", select your XLSX spreadsheets, adjust the options if you want, and press "Convert to CSV". The CSV downloads immediately; with several files you can download everything as one ZIP.
Is this XLSX to CSV converter free and safe?
Yes. It is completely free, with no sign-up, no daily limit and no watermark. The conversion runs inside your browser, so your spreadsheets never leave your phone or computer and nothing is stored on News Appite's servers.
Are formulas, formatting and all sheets kept?

What is the difference between XLSX and CSV?
XLSX (Microsoft Excel Workbook (Office Open XML)) is a spreadsheet workbook best suited to working with data in Excel, Google Sheets and accounting or GST software. CSV (Comma-Separated Values) is a plain-text table best suited to importing data into databases, CRMs, Tally, mailing tools and Python or R.
Is there a file size limit?
There is no upload limit, because nothing is uploaded. The practical limit is your device's memory: files of a few hundred megabytes work on most computers, and phones handle smaller files comfortably.
