Limits and behavior

Columns are the union of object keys in observed order. Scalars only; null and missing cells become empty. Spreadsheets may execute formula-like cells: import as text when processing untrusted data. Maximum total input 1 MB, output 3 MB, JSON nesting 64 levels. Processing stays in your browser worker. Input is limited to 1 MB and output to 3 MB. No input content is saved by CraftAI.

JSON array to CSV file conversion

Convert a JSON array of objects into comma-separated values for spreadsheet-style workflows. This JSON-to-CSV converter is useful for exported records, lightweight data analysis and tabular sharing.

Can any JSON document become a CSV table?

Not every structure maps cleanly to columns. Use an array of objects with sensible properties and inspect how complex or missing fields appear in the CSV.
