Empty vs null in CSV→JSON (no upload)
Decide how to represent empty values in JSON and keep downstream validation consistent.
Null vs empty strings in CSV to JSON Playbook
Null vs empty strings in CSV to JSON. Step-by-step no-upload workflow: validate, locate root cause, fix quickly, and verify.
TL;DR: Validate -> locate exact failing spot -> fix the minimal part -> re-validate.
Execution steps
- Validate input locally. Start with a validator or parser-friendly converter.
- Locate root cause. Use line/position/error token to isolate one failing place.
- Apply a minimal fix. Do not refactor all content at once.
- Re-validate and continue. Once clean, convert/export safely.
