JSON → CSV
JSONConvert 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.
