Convert JSON to CSV Online
Convert JSON arrays into clean CSV for spreadsheets, databases, and data review without sending data to a server.
Problem
A JSON response or export needs to be opened in a spreadsheet or loaded into a tabular workflow.
What to do
JSON often nests data, while CSV expects rows and columns. Convert the array, flatten nested fields if needed, and inspect the generated headers before export.
- 1Paste the JSON array or upload a file.
- 2Choose delimiter, quote, and flattening options.
- 3Copy or download the CSV output.
Use the browser tool
JSON → CSV converts a JSON array of objects into clean, spreadsheet-ready CSV. It flattens nested objects to dotted columns, lets you choose the delimiter, quote style, boolean and null formatting, and header casing — then copy or download the result. A fast, private way to get API responses into Excel or a database.
