- Why JSON needs a different kind of "extraction"
- A JSON file is already structured data, the challenge isn't reading text off a page, it's turning a nested array of objects into a flat table that makes sense in a spreadsheet, with consistent columns even when some records are missing fields.
- Datafromfile parses JSON files directly (deterministically, not via AI guessing) and infers a consistent set of columns from your records, so the result is a real table you can edit and export, not a JSON viewer.
- When this is useful
- Step-by-step
- 1. Upload your `.json` file to Datafromfile. 2. The extraction engine reads the array of records and builds a table, inferring column types (text, number, currency, date) from the actual values. 3. Review and edit the table in the workspace, fix any misclassified column type or clean up individual values. 4. Export to XLSX, CSV, or back to JSON if you just wanted it cleaned rather than converted.
