Guide & examples

About JSON to CSV

Turn a JSON array of objects into CSV with a combined set of column headers.

When to use it

Turn a small array of API records into rows for a spreadsheet.

JSON to CSV example
JSON: [{"name":"Demo","count":2}]

CSV:
name,count
Demo,2

How to use it

  1. Paste an array of JSON objects.
  2. Choose Convert to CSV.
  3. Copy the CSV into a file or spreadsheet.

Limits & privacy

Up to 5,000 rows and 256 columns are supported. Quote highly precise numeric values to preserve them. Nested objects become JSON text. Formula-like strings are escaped for safer spreadsheet use.

Use this tool from the API reference or connect through the SDK, CLI, SSH, or MCP. Hosted calls share your plan allowances.
