JSON Records to Clean CSV

Convert compatible JSON object records to a table, keep the first matching exported row and download protected CSV. Choose explicit settings, review the real downloaded output and keep your original for retry.

• Requires a nonempty array of objects: at most 10,000 records, 200 columns and 200,000 data cells. Duplicate keys/invalid Unicode reject. Unsafe/high-precision numbers reject; quote them as strings. Safe number spelling normalizes (-0 to 0, 1.10 to 1.1). Keys are unioned; missing/null become empty cells and nested values become JSON text. Intermediate CSV must fit the next step's 5 MiB input limit. Final formula protection preserves complete bounded signed decimal/exponent numbers and adds an apostrophe to formula or control-prefixed expressions. CSV/TSV imports may infer types; import identifier columns as text. Protection OFF retains literal expressions with spreadsheet execution risk.
