No account · Nothing to upload · 500K rows free, 10M on Pro

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 CSV, Excel, ODS, and Parquet files without the freezing, spinning, or "not responding". Hundreds of thousands of rows, up to 10 million on Pro.

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. It all works 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 straight into your spreadsheet app, and formulas for calculated columns and filters when you want them.

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.

See it as a chart

Build and explore charts over all your rows, free and right on your device. Export them as PNG or SVG with Pro.
