API samples, spreadsheet exports, and quick table-to-JSON conversions.

Use CSV ↔ JSON

Updated: 2026-05-08

Example 1: Header row CSV → JSON array

Turn a first-row-headers CSV into an array of objects.

Inputs

  • customers.csv

Steps

  1. Upload or paste.
  2. Check the delimiter.
  3. Copy JSON output.

Output

[{...}, {...}]

Example 2: JSON list → CSV for Excel

Flatten a small JSON list to edit in a spreadsheet.

Inputs

  • list.json

Output

list.csv

Tips

  • Quoted fields and odd line breaks are fragile—prefer UTF-8 sources.
  • Very large files can exceed browser memory; use CLI tools then.
