Validate a JSON Config
A single stray comma in package.json or a config file can fail a whole build pipeline. Validate first and get the exact line and column of the error.
- Paste the JSON you are about to commit.
- Run the validator — it parses strictly and reports position information.
- Fix the reported location and re-validate until it passes.
