Open the CSV Excel can't.
Clean up, reshape, and explore huge spreadsheets that freeze Excel — right in your browser. Your data stays on your computer and never gets uploaded.
No account · Nothing to upload · Handles millions of rows
Never uploaded
Your data is processed on your machine, not on our servers.
Nothing to leak
We never receive your files, so there is nothing for us to store or expose.
No tracking
No ads, no cross-site trackers, no profiling of your data.
Everything you need to clean up your data
A focused workspace for fixing and reshaping data you can't risk sending to the cloud.
Open files that crash Excel
Load and scroll spreadsheets with hundreds of thousands — even millions — of rows, without the freezing, spinning, or "not responding".
Clean up messy data fast
Fix inconsistent capitalization, tidy dates and emails, fill in blanks, remove duplicates, and split or combine columns — in a few clicks.
Reshape and summarize
Filter, sort, total up, build pivot tables, and combine or compare files — all from simple menus, with no formulas to memorize.
Your data never leaves your device
Everything happens on your own computer, right in your browser. Your files are never uploaded, stored, or seen by anyone — including us.
Works like a spreadsheet
Familiar keyboard shortcuts, copy and paste straight to and from your spreadsheet app, and a formula bar for when you want one.
Every step is saved
Each change becomes a saved step with the exact query it ran. Reopen your work later and it’s all still there — pick up right where you left off.
Three steps, zero uploads
