Fix mixed delimiters in CSV (no upload)
When some rows use commas and others use semicolons/tabs, parsing breaks. Use sampling and re-export strategies.
Mixed delimiters in one file
Fix Mixed delimiters in one file with a repeatable workflow: stabilize structure, spot-check a sample, then convert/export locally (no upload).
TL;DR: Validate locally, pinpoint the failing spot, apply the minimal fix, then validate again.
Fast no-upload workflow
- Validate the input (strict rules, correct encoding, correct delimiter/quotes).
- Locate the exact position/line reported by the parser or validator.
- Fix the smallest broken part (often a quote, escape, delimiter, or a truncated copy/paste).
- Re-validate and only then convert/export.
