Data tool
CSV Cleaner
Paste or upload CSV text, trim messy cells, remove blank rows, remove duplicate rows and download a cleaner file for spreadsheets, uploads or reports.
This is a lightweight browser tool for simple CSV cleanup. Always review important data before importing it into another system.
What it fixes
The cleaner trims extra spaces, removes fully blank rows and can deduplicate exact matching rows. This is useful before importing lists into spreadsheets or CMS tools.
What it does not do
It does not validate business rules, repair every malformed export or understand private database formats. For critical data, verify in a spreadsheet afterward.
