Gridzu is a friendly data workbench. Drop in a spreadsheet or CSV, tidy it with one click, cross-check two files for differences, and roll back to any version — all on your own computer, fully offline.
Spreadsheets were designed decades ago — for small tables and hand-typed formulas. The data we all work with outgrew them years ago, but the tools never caught up. They still freeze on big files, can't truly compare two datasets, forget everything the moment you close them, and turn teamwork into a graveyard of final_v3_FINAL.xlsx.
Gridzu is what should have happened a long time ago — not a spreadsheet with more buttons, but the way these tools should have evolved.
The everyday things spreadsheets still can't do — built in from the start.

The speed and rigor of a real database, with the friendliness of a spreadsheet — and no formulas to learn.
A real database engine runs under the hood, so millions of rows stay smooth — files that would freeze a normal spreadsheet.
Everything runs on your machine — your files are never uploaded. A free account just unlocks the app; your data stays entirely local.
Point-and-click cleanups, visual comparisons, and recorded recipes — no formulas, SQL, or code to learn.
Match two tables by a key column and instantly see what changed, what's missing, and what's new — color-coded, with a one-click "differences only" view.
Gridzu remembers your workspace across restarts and lets you save named versions. Made a mistake? Revert to any earlier version. Want to experiment? Branch off safely.
If you wrangle data files but don't want to write formulas, SQL, or code — this is for you.
