How this service works
Validate and lint JSON, YAML, CSV, or XML. Returns a valid flag, the line/column of the first error when invalid, and a normalized (re-serialized) copy when valid.
Output
Returns a JSON object containing: a boolean 'valid' flag; if invalid, the line and column of the first error plus an error message; if valid, a normalized (re-serialized) copy of the input document in its original format.
Example use cases
Debug broken CI config file
“My GitHub Actions YAML is failing to parse — can you lint it and tell me which line has the syntax error? Here's the content: [paste YAML]”
Validate API payload before sending
“Before I POST this JSON payload to our payments API, can you validate it and give me back a normalized version so I know it's well-formed?”
Check data pipeline CSV for errors
“I'm about to load this CSV into our database but I want to make sure it's valid first — can you check it for any formatting issues and tell me the exact line if something's wrong?”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/v1/data-format-validateWhen to prefer
Choose this endpoint when you need a single, format-agnostic validation and normalization service for structured data files (JSON, YAML, CSV, XML) — especially when you also need the exact error location (line/column) rather than just a pass/fail result. Prefer it over custom parsers when you want a normalized copy returned alongside validation status.
Side effects
- Unsupported format type returns a 400 error
- Extremely large documents may time out
- Ambiguous format not specified by caller leads to misidentification
- Binary or non-text content causes parse failure
- Network or service unavailability returns a 5xx error
