From opening a file to sharing it with your team — without leaving Gridzu, and without writing a formula.
Import CSV, TSV, and text files by drag-and-drop or a click. A fast, virtualized grid stays smooth even at millions of rows.
Click a header to sort. Search across every open table at once, with per-table match counts and jump-to-result.
Double-click any cell to change it. Add, insert, duplicate, or delete rows and columns. Undo and redo everything.
Remove duplicate rows, trim stray spaces, clear blank rows, and run find & replace with a live match count.
Group rows into labeled, colored bands so big tables stay organized and easy to scan.
Reconcile two tables, validate against a list, find duplicates, compare two columns, compare structure, or compare totals by group.
Record a cleaning sequence once, then replay it on next week's file in a single click. Steps follow your columns by name.
Make Gridzu yours — rebind any keyboard (and mouse) shortcut to match how you work, or keep the sensible defaults.
Your workspace persists between sessions. Save named versions, revert to any point, and branch to experiment safely.
Back up and share datasets as clean per-table files. Send changes for review and approve or auto-merge safe edits.
Send your cleaned data back out as CSV whenever you need it elsewhere.
All processing happens on your machine. Nothing is uploaded unless you explicitly choose to share via GitHub.
A fast built-in engine keeps even multi-million-row files responsive and smooth.
Six ways to cross-reference your data — each result is color-coded and filterable down to just the differences.
Match two tables by a key and see field-level differences: matched, changed, only-in-A, only-in-B.
Check whether each value in one table exists in a reference list in another.
Find rows in one table that share the same key, grouped together.
Compare two columns of one table, row by row.
Compare the column names and types of two tables.
Count or sum by a group, then compare the totals between two tables.
