JSON

Convert JSON arrays to CSV format

A non-technical teammate rarely wants a raw API response. They want a spreadsheet, and this turns a JSON array of objects into CSV rows that open cleanly in Excel or Sheets. Nested objects get flattened into dotted-key columns like `address.city` so structure isn't silently lost, though deeply nested arrays of objects can end up stringified into a single cell since CSV has no real concept of nesting. Column order is generally derived from the first object's keys, so a dataset where later records introduce extra fields is worth double-checking before you hand off the export. It only runs in one direction: for the reverse, look for a CSV-to-JSON tool elsewhere in the catalog.

How to use JSON → CSV

  • 1.Paste a JSON array of objects to convert it into CSV rows you can open in Excel or Google Sheets.
  • 2.Use it to quickly turn an API's JSON response into a spreadsheet for a non-technical teammate.
  • 3.Flatten nested JSON objects into dotted-key columns (e.g. `address.city`) so nested data doesn't get lost in the CSV export.

Frequently asked questions

What happens with nested objects or arrays inside the JSON?
Nested objects are flattened into dot-notation columns where possible; deeply nested arrays of objects may end up stringified in a single cell since CSV has no concept of nesting.
Does the column order match the JSON key order?
Columns are generally derived from the keys of the first object, so if later objects have extra fields not present in the first, you may need to check the output carefully.
Is my data uploaded to a server?
No, the conversion happens entirely in your browser.
Can I convert CSV back to JSON?
This tool is one-directional (JSON to CSV). Check the tools list for a CSV → JSON converter if you need the reverse.
