Pivot, unpivot, split, dedupe, fill down, fix text-as-numbers, standardize dates — the everyday cleanup, point-and-click.
TransformSafe · Coming soon
The spreadsheet work Excel can't do — safe on your own machine.
Pivot, clean, join, and chart your data without wrestling Excel or pasting it into a public AI. Easy as ChatGPT, safe as your own spreadsheet.
The pivot table, the cleanup, the VLOOKUP that never quite works — the spreadsheet work everyone needs and most people can't do in Excel. So it ends up pasted into a public AI chat to "just figure it out." The moment it lands there, the data has left your control.
TransformSafe does that work the safe way. Drag a sheet in, make a few choices, and download the result — and your data never leaves your machine.
What it does
Drag a sheet in. Make a few choices. Download the result.
Reshape & clean
Combine & chart
Join files (the VLOOKUP-killer), stack sheets, compare lists, and turn the result into a clean chart.
Save the recipe
Save a sequence of steps and re-run it on next month's file in one click — the recipe is saved, never your data.
Why it's different
Safe and easy — not one or the other.
Excel is safe but hard. A public AI chat is easy but unsafe. TransformSafe is the only option that's both.
01
Nothing uploads
Your data is processed right in your browser, on your own machine. Open the network tab and watch nothing leave.
02
Nothing is stored
Results live only while the tab is open. Close it and they're gone — there's nothing to breach.
03
No model sees your data
Every operation is plain, deterministic computation — never an AI reading your numbers.
Launching soon.
TransformSafe is in the last stretch before launch. When it opens, this is where you'll start.
