About the XLS to CSV Converter
Need to turn a XLS file into CSV? This free converter changes XLS spreadsheets into CSV in a few seconds, right in your browser. People usually convert because XLS is a legacy format limited to 65,536 rows, 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 XLS to CSV Converter
- Click "Choose files" or drag your XLS 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 XLS 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.
Frequently asked questions
How do I convert XLS to CSV?
Click "Choose files", select your XLS 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 XLS 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?
Every sheet is converted (or only the first, if you choose). Formulas are exported as their current values, and cell colours and fonts are not carried over because formats such as CSV, JSON and SQL cannot store them.

What is the difference between XLS and CSV?
XLS (Microsoft Excel 97–2003 Workbook) is a legacy binary spreadsheet best suited to older Excel versions, legacy ERP and bank systems and portals that only accept .xls. 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.
How do I convert XLS to CSV in Python?
