JSON Validator

Validate JSON syntax and display the root type.

1. Paste a structured text sample or open a local text data file.
2. Supply relevant field names or settings if needed.
3. Run the transformation, validate output and download it.

These local format utilities do not connect to your databases or fetch remote URLs. JSON and CSV files have limits of 120 KB input and 250 KB output; CSV is limited to 5,000 rows and 200 columns. CSV exports neutralize spreadsheet formula-looking cells. JWT payload decoding does not verify signatures.
