Cleaned preview
Run the sample to see a preview.
The preview shows up to 20 rows. Downloads include all retained rows and use comma separators. Fields beginning with spreadsheet formula characters are prefixed with an apostrophe in the download. This can change spreadsheet interpretation; review before use and do not remove the protection when sharing untrusted data. Exact duplicates compare complete rows after optional trimming. This tool does not merge similar project names or validate listing facts.
