JSON ⇄ CSV Converter — Arrays to Spreadsheets

API exports to Excel-ready CSV (and back) — headers auto-detected, quoting handled, all local.

Quick answer: Free JSON→CSV: paste an array of objects, get clean CSV with auto-detected headers; swap to convert back.

Output

How to use

About this tool

The API-gives-JSON, Excel-wants-CSV problem, solved both ways: paste an array of objects — headers appear automatically — or paste CSV and get JSON back via swap. Proper quote-escaping included.

FAQ

Nested objects?

Flattened via dot-paths (user.name) — spreadsheet-friendly.

Excel commas inside values?

Quoted and escaped per RFC-4180.

Huge files?

Tens of thousands of rows fine — local compute.

Back to JSON?

Swap → paste CSV → convert: typed as strings.

Privacy?

Nothing leaves your device — sensitive exports safe.

Numbers in JSON output?

CSV→JSON outputs strings; numeric typing stays simple and predictable.
