What this machine handles
- Missing commas, quotes and closing brackets
- Trailing commas and JavaScript-style comments
- Single quotes and Python-style booleans
- Duplicate-key detection before any value is lost
Before you upload
Repairs are syntactic. Missing values can become null; inspect the assumptions. Duplicate keys are rejected instead of silently discarding values. Schema validation is not included yet.
Original uploads are processed in memory. Generated files and previews are private, expire after 24 hours, and are removed by the cleanup process. How file handling works
