Features
Everything a spreadsheet janitor wishes existed
Built for the people who inherit messy exports — not for data engineers with a week to spare.
AI recommendations that explain
Every issue comes with why it matters, its business impact, a recommended fix, and a confidence score. CleanIQ educates while it cleans.
Private by architecture
Parsing and cleaning run in your browser via Web Workers. Your raw data is never uploaded, stored, or seen by anyone — including us.
Quick Clean
Apply every high-confidence fix in one click: duplicates, whitespace, casing, empty rows. Preview the diff, then export.
Data Health Score
A 0–100 score summarizes the state of your file. Watch it climb as issues are resolved — and share the before/after.
Cleaning Templates
Save an entire workflow — like “Monthly Sales Cleanup” — and re-apply it to next month’s file in a single click.
Every messy-data classic, covered
Duplicates, missing values, invalid emails and phones, mixed date formats, empty rows and columns, stray whitespace, inconsistent text.

FAQ
Questions, answered
Does my data really stay in my browser?
Yes. Files are parsed and cleaned locally using Web Workers — they are never uploaded to our servers. Only anonymous column statistics (never raw rows) are sent to power AI recommendations, and only if you use them.
What file types are supported?
CSV and Excel (.xlsx). Excel support loads on demand, so it never slows down the app for CSV users.
Will CleanIQ change my data without asking?
Never. Every fix shows a before/after preview and requires your confirmation. Everything is undoable, and Quick Clean only applies high-confidence fixes — which you can also preview and revert.
What are Cleaning Templates?
A saved, reusable cleaning workflow. Clean this month’s export once, save the steps as “Monthly Sales Cleanup”, and apply the exact same pipeline to next month’s file in one click.
How big can my files be?
The browser engine comfortably handles files up to ~50 MB / 500k rows. Server-assisted processing for larger files is planned for the Business plan.
