About the Excel to XLS Converter
Need to turn a XLSX file into XLS? This free converter changes XLSX spreadsheets into XLS 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 XLS gives you an Excel 97–2003 workbook. XLS files open in every version of Excel, LibreOffice Calc, Google Sheets and WPS Office.
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 XLS 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 XLS". The conversion runs on your device and shows its progress.
- Download each XLS file, or use "Download all (ZIP)" when you converted several.
- Open the result in every version of Excel or LibreOffice Calc to check it; your original XLSX is never changed.
Tips & benchmarks
- XLS holds at most 65,536 rows and 256 columns per sheet; larger data is cut at that limit.
- Merged cells are unmerged and their value is kept in the first cell, which keeps the data easy to filter and import.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the XLS to a website or government portal.

What is the difference between XLSX and XLS?
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. 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.
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.
