Free tier from install, no credit card. Clean up to 50 rows a run, up to 10 runs a month, plus a 7-day trial that raises the limit to 5,000 rows a run and opens the AI cleaning tools.
Fair billing: 135 hours of active processing. Only the seconds Flookup spends working reduce the balance. Unused time never expires.
135 Hours of Active Processing
Only the seconds Flookup spends working reduce the balance. Time you spend reading or editing the sheet does not. Each run is capped at 6 minutes, and unused balance never expires.
A run that stops early still counts the time it used. When the balance reaches zero the free tier applies again, and nothing renews. If you need more time, buy another pass with the same email and the hours add to your balance.
Who Uses Flookup?
Flookup is built for people who clean and match records in spreadsheets. The common thread is a list of names, organisations or records that do not quite match, and a deadline.
Researchers and Academics
Match author, institution and survey-response names across datasets without exporting to another tool.
Librarians and GLAM Teams
Clean catalogue records, authority files and collection metadata while keeping the work visible in the sheet.
Data Analysts and Operations
Deduplicate customer, supplier and product lists, then standardise the variants that exact matching misses.
The same workflow fits sales, finance, HR and admin teams that need to reconcile lists before a report, migration or upload.
