JSON to CSV: Flatten API Data Into a Spreadsheet Table
JSON is great for code and awkward for eyeballing. Flatten it into CSV when you want to sort, filter, or share it as a table.
What is the JSON to CSV Converter?
Paste JSON made of objects and get a CSV file-style table with one header row and one row per object. Fields that contain commas, quotes, or line breaks are quoted automatically so the result opens correctly in a spreadsheet. It is the quick way back when an API gives you JSON but your next step needs a table.
How to use it
- Paste a JSON array where every item is an object.
- Click Convert to CSV.
- Check the header row covers every key used.
- Copy the CSV into a spreadsheet or a .csv file.
Worked example
[{"name":"Ada","age":36}] becomes a CSV table with the header name,age and the row Ada,36.
How do I turn JSON objects into CSV?
Paste the JSON array, convert, and you get a header row plus one CSV row per object, with tricky values quoted so nothing shifts columns.
Frequently asked questions
Can it convert a single object instead of an array?
Yes. A single object is wrapped into a one-row table automatically.
What happens to values with commas?
They are wrapped in double quotes, with any inner quotes doubled, so spreadsheets read them as one cell.
