🔄 JSON to CSV Converter
Convert a JSON array of objects to CSV, or turn CSV back into clean JSON.
About this JSON to CSV Converter
Developers live in JSON while spreadsheets and reports live in CSV — this converter bridges the two. It flattens a JSON array of objects into a tidy CSV table, collecting every key into the header, and it parses CSV back into JSON objects using the header row as property names, handling quoted fields correctly.
How to use it
- Choose the direction: JSON to CSV, or CSV to JSON.
- Paste your data into the Input box.
- Click Convert.
- Copy the result from the Output box and check the row count below.
Example
The JSON [{"name":"Ali","age":30}] converts to the CSV text name,age on one line and Ali,30 on the next — ready to open in any spreadsheet.
Frequently asked questions
What happens to values with commas or quotes?
They are wrapped in double quotes and inner quotes are doubled, following standard CSV rules, so spreadsheet apps read them correctly.
Do CSV numbers become JSON numbers?
No — CSV has no data types, so every value comes back as a string. Convert them in your code if you need numbers.
What if my JSON objects have different keys?
The CSV header is the union of all keys across all objects; missing values are simply left blank.
