JSON to CSV Converter Online
Convert JSON arrays and objects into CSV rows without uploading data. Use it for spreadsheet exports, API samples, mock data, and quick developer cleanup.
A JSON to CSV converter turns object fields into column headers and object values into rows.
It is the reverse workflow of a CSV to JSON converter.
Array of objects
Use a JSON array where each item has similar keys for the cleanest CSV table.
Stable keys
Flatten nested objects when you want nested values to become predictable CSV columns.
JSON object keys -> CSV columns
Objects with missing fields receive blank cells. Values containing quotes, line breaks, or delimiters are escaped with standard CSV quoting.
CSV is a table format, so deeply nested or irregular JSON may need flattening before it becomes useful in a spreadsheet or import workflow.
This tool creates CSV output only. It does not validate target database schemas or spreadsheet formulas.
API response exports
Turn JSON arrays from API examples into CSV rows for spreadsheets or QA notes.
Mock data cleanup
Convert object fixtures into table data for docs, demos, or imports.
Spreadsheet handoff
Prepare CSV output from structured JSON before sharing with non-developer teammates.
Developer debugging
Flatten and inspect object data in a table-friendly format.
Example
An array of user objects with name, role, and city fields becomes a CSV table with three columns.
Assumption
Each object is treated as one row and object keys become candidate headers.
Limitation
Highly nested arrays, mixed object shapes, and binary values may need custom export logic.
Does it upload JSON?
No. Conversion runs in the browser.
Can it convert a single object?
Yes. A single object is treated as one CSV row.
Can it handle nested objects?
Yes. Enable flattening to turn nested keys into dot notation columns.
Is this the same as CSV to JSON?
No. This converts JSON into table output; CSV to JSON converts table rows into JSON objects or arrays.

Move from structured JSON to spreadsheet-friendly CSV and back to cleanup tools when needed.
