The Problem

Every team wastes hours cleaning spreadsheets

You receive an export from an ERP, a bank, a CRM, or a government portal. Before you can do anything useful, you spend 30 to 90 minutes fixing it by hand.

Garbled text

"émilie Tremblay" instead of "Émilie Tremblay". Encoding breaks every time you export from legacy systems.

Mixed date formats

Some columns use MM/DD/YYYY, others DD/MM/YYYY, others "Jan 15, 2024". Good luck sorting that.

Messy currency values

"$1,234.56", "1 234,56 €", "USD 990.00" all in the same column. Your pivot table breaks.

Hidden duplicates

Rows that look identical but have trailing spaces, different casing, or invisible characters.

Junk rows & headers

Bank statements with 15 rows of metadata before the actual data starts. Report footers mixed in.

Typos in categories

"Nroth America", "North Amrica", "north america". Same thing, three spellings.

Real Example

A real financial export, before CleanSheet

This is what a typical ERP export looks like when you open it. Garbled text, mixed dates, broken numbers, duplicates everywhere.
