JSON ⇄ CSV Converter

Working with data often requires switching between JSON and CSV formats. JSON is perfect for structured objects, while CSV is ideal for spreadsheets and tabular reports. QuickTools JSON ⇄ CSV Converter handles both conversions entirely in the browser, no server-side code needed.

Main Features

  • Bidirectional: convert JSON arrays to CSV and CSV text back to JSON.
  • Automatic headers: extracts keys from the first JSON object as CSV columns.
  • Privacy-focused: all data stays on your device.
  • Large-scale support: optimized for handling big payloads quickly.

How to Use

  1. Select your mode: JSON → CSV or CSV → JSON.
  2. Paste your JSON array ([{"name":"Alice","age":30},...]) or CSV text (name,age\nAlice,30).
  3. Click Convert to generate the result.
  4. Copy or download the output for further processing.

Use Cases

• Import/export between web APIs and Excel
• Quick data cleanup and transformation
• Testing API endpoints
• Feeding CSV into BI tools

Quality Tips

  • Ensure uniform object keys in JSON.
  • Include a header row in CSV before conversion.
  • Watch out for commas inside quoted fields.
