About our excel tools
Accountants, shop owners and analysts spend hours on the same spreadsheet chores: converting a Tally or portal export to CSV, merging twelve monthly files, splitting a sheet by branch, removing duplicate rows before a GST return. These tools do all of it in the browser, with no install and no upload, which keeps customer data and salary sheets on your own machine. XLSX, XLS and CSV are all supported, and results download as clean files you can open in Excel, LibreOffice or Google Sheets.
Excel tools — frequently asked questions
Will my spreadsheet be uploaded to a server?
No. The workbook is parsed in your browser and the converted file is generated there too, so the data stays on your device.
Do formulas survive the conversion?
Values are kept, formulas are not — CSV and JSON have no concept of a formula. Keep the original workbook if you still need the calculations.
How large a file can I open?
Files with a few hundred thousand rows work on a normal laptop. Very large workbooks depend on available memory, so split them first if the tab slows down.
