Normalize CSV headers (no upload)
How to normalize header keys to stable JSON fields without losing meaning.
Normalize CSV headers (case/spaces/symbols)
Fix Normalize CSV headers (case/spaces/symbols) 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.
