Spreadsheet Editor
A free online spreadsheet editor — work with formulas, rows and columns, then export to .xlsx. Everything runs entirely in your browser — your files are never uploaded to a server, so your data stays private on your device.
For when you just need to crunch some numbers
Tracking a budget, building a quick invoice, totaling up expenses, or sorting a list of names and figures — these are everyday tasks that call for a spreadsheet, not a heavyweight application you have to install and sign into. OfficePad’s spreadsheet editor gives you the rows, columns and formulas you’re used to from Excel, ready the moment you open the page, so you can get the numbers sorted and move on.
Open, edit and export .xlsx files
You can open spreadsheets you already have in .xlsx format, make your changes using familiar formulas and functions, and export the result back to .xlsx so it opens correctly in Excel, Google Sheets or any other spreadsheet program your colleagues use. Because everything runs locally in the browser, your figures — whether personal budgets or business numbers — never pass through an external server.
