Decision Guide

Best for

  • Arrays of flat or lightly nested objects.
  • Exporting data for reports or bulk edit in spreadsheets.

Avoid when

  • You need deep nested objects flattened with custom key paths.
  • Data is highly relational (consider a proper export from your DB).

Example

Array of objects to CSV

Input

[{"name":"Alice","score":95},{"name":"Bob","score":87}]

Output

name,score
Alice,95
Bob,87

First row is headers; each object becomes one row.

FAQs

Is my JSON sent to a server?

No. Conversion runs entirely in your browser. Your data never leaves your device.

What about nested objects or arrays?

Nested values are JSON-stringified in the cell. For flat spreadsheets, use shallow objects.
