One workbook. A focused tool for every mess.
You never face a wall of buttons. TidyCell reads your file and puts the right tool in front of you — then keeps every fix as an undoable step you can stack.
It reads your file
Drop a file and see a plain-English list of what's wrong, ranked by impact — with the exact tool to fix each one.
You approve every change
Every tool previews before/after. Applied fixes become steps you can undo or stack — the file evolves, you stay in control.
Your real file, back
Cleaning runs in your browser. Download the same workbook — formulas, formats, charts and every sheet preserved.
Every tool, grouped the way you think
Not by what our code does — by what you're trying to do.
Tidy Cleanup
Spaces, casing, dates, blanks & duplicates.
Numbers & Currency
Text like “$1,200” → real numbers.
Normalize Values
Merge “CA / Calif. / California” into one.
Find a Problem
AI reviews only the values that stand out.
Compare to Original
Every change, cell by cell.
Require Values
Set aside rows failing a rule (never deleted).
Column Parsing
Split one crammed column, by example.
Split Sheets
Divide one sheet by date or value.
Build a Column
Concat, coalesce, arithmetic, slugify.
Ask TidyCell
Plain-English questions about your data.
Filter & Read
Slice, search & sort every column.
Convert / Export
xlsx, CSV, JSON, Markdown, SQL…
…and more, added often. Locked tools always show what they'd do to your file before you upgrade.
We tidy. We never rebuild.
Every fix is a diff applied on top of your actual workbook — not a fresh export. It's the one thing spreadsheet cleaners never get right, and it's free in every plan.
