]Infer a reviewable JSON Schema from real example records. Produces a JSON Schema 2020-12 draft from observed values, with unions for mixed types and required keys present in every observed object of that shape. Empty arrays cannot imply an item type. It does not certify unseen records, infer formats or validate a complete JSON Schema specification. Bounds: 20 levels, 50,000 visited nodes.
Prepare the input
Infer a reviewable JSON Schema from real example records.
Paste the supported structured data or log text. The sample loads only when explicitly selected and can be undone.

Keep the useful output
Review the summary and result records. Transformation tools retain separate change, rejected-record or diagnostics datasets where relevant. Choose the dataset before exporting; a report and a cleaned dataset serve different purposes.
CSV exports protect formula-like text. JSON keeps data portable without making an Excel workbook. Reports and editable backups may contain private source values; download only what you intend to share. No automatic account storage or server processing is used.
