Messy spreadsheet in.
Your real file back out.
Drop an Excel or CSV file and TidyCell shows you exactly what's wrong with it. Fix one thing at a time, watch every change, and download the same file back — formulas, formatting and every sheet still intact.

You shouldn't have to know what tool you need.
Most cleaning tools drop you into a wall of buttons. TidyCell reads your file the second you drop it and tells you, in plain English, what's actually wrong — then puts the one fix you need right in front of you.
1. It reads your file
The moment you drop a file, TidyCell scans it locally and lists what it found: mixed dates, numbers stored as text, duplicate rows, blank columns.
2. You pick one fix
Tap the fix you want — or search for anything. Every change is previewed before/after. Nothing happens you didn't approve.
3. You get your file back
Download the same workbook — formulas, number formats, charts and every sheet preserved. We tidy; we never rebuild.
A tool for the one thing you need
Tidy Cleanup
Trim spaces, fix casing, standardize dates, drop blanks & dupes.
Column Parsing
Split one crammed column into clean, named columns — by example.
Numbers & Currency
Turn “$1,200” and “45%” into real numbers Excel can sum.
Find a Problem
Scan locally for values that stand out; AI reviews only the top few.
Charts & Dashboards
Turn a cleaned sheet into AI-designed charts you can drill into.
Convert / Export
Download as .xlsx, CSV, JSON, Markdown, SQL and more.
We give you back your real file.
Other cleaners rebuild your data from scratch and hand you a stripped-down copy — formulas gone, formatting gone, other sheets gone. TidyCell edits your actual workbook in place. Every fix is a diff applied on top of the file you uploaded.
- Formulas, number formats & merged cells survive
- Charts, pivots and images preserved byte-for-byte
- Every worksheet comes back, not just the one you cleaned
Try it on your messiest file.
