GSTR-1 JSON Validator
Verify your JSON files before uploading them to the GST Portal to avoid tedious correction steps. Validates JSON syntax and basic GST structural schemas.
Why Validate Returns Offline?
The GST portal can often take several minutes to process an uploaded JSON file, only to return an error report if the schema doesn't perfectly match expectations. This validator checks for core GST structural integrity (e.g. valid GSTIN formats, appropriate tax rates, valid date formats) completely offline.
Frequently Asked Questions
- Does this replace the official offline tool?
- No, this is a supplementary tool to pre-check structural integrity. It helps you catch common formatting or nesting errors before you attempt an upload on the official GST portal.
- Will this catch incorrect tax calculations?
- This tool primarily checks the JSON schema, structure, GSTIN formats, and basic data types. It does not perform deep accounting calculations (like verifying if your tax amount precisely equals the taxable value * rate).
