How do you convert JSON to CSV?

Flattening JSON to CSV starts with the header: the tool walks every object in your array, collecting keys in first-seen order, so records with mismatched fields still line up under one combined header row. Cells containing commas, double quotes or newlines get wrapped and doubled per RFC 4180. Nested objects are serialised as JSON text inside their cell rather than silently dropped.

How to use the JSON to CSV

  1. 1 Drop in a JSON array of objects, or one object on its own.
  2. 2 The header assembles itself from every key found across the records.
  3. 3 Look over the rows; awkward values arrive already quoted.
  4. 4 Grab the CSV and save it with a .csv extension.

What you can use it for

  • Exporting API responses into a spreadsheet.
  • Handing JSON records to Excel or Sheets users.
  • Sharing structured data with non-technical colleagues.
  • Preparing a CSV upload from JSON output.

Frequently asked questions

What decides the column order?
First appearance wins. The converter records each new key as it walks the array, so columns follow the order keys first show up across your objects.
How are nested values handled?
An object or array value is written into its cell as compact JSON text. CSV stays flat, but nothing is discarded.
Will a lone object work?
Yes. It produces a two-line file: one header row and one data row.
