About this tool
JSON to CSV Converter — CSV is a flat table, while JSON can contain nested objects and arrays. A reliable conversion depends on rows having compatible fields and on a clear policy for nested values.
Review delimiters, quoting, line endings, and character encoding before importing the result into another system.
How to use it
- Paste an array of JSON objects.
- Run the conversion and inspect the generated columns.
- Download or copy the CSV, then test the import settings in the target program.
Example
[{"name":"Ali","score":9},{"name":"Mona","score":10}]name,score Ali,9 Mona,10
Open the result using UTF-8 and the correct delimiter in your spreadsheet.
Common uses
- Move simple API data into a spreadsheet.
- Create a quick table for review.
- Prepare small test exports.
What to know
- Complex nested JSON cannot always be represented without losing structure.
- CSV formulas can be interpreted by spreadsheets; review untrusted cells before opening.
