Free CSV & Data Tools Online
Work on CSV exports locally: sort columns, drop empty rows, filter records, and convert tables to JSON. Nothing is uploaded, which matters when spreadsheets include emails, invoices, or customer IDs.
These CSV tools assume a header row and comma-separated fields. Quoted commas are preserved. Start with the validator if a file fails to open in Excel, then sort or convert. For JSON APIs, use CSV to JSON or JSON to CSV instead of rewriting rows by hand.
