What is a JSON to CSV Converter?
API responses come as JSON arrays; analysts want spreadsheets. This converter takes the union of every object’s keys as the header row and quotes fields correctly so Excel and Google Sheets open the result cleanly.
Nested objects are serialized as JSON strings inside their cell — visible, not silently dropped.
How to use the JSON to CSV Converter
- Paste a JSON array of objects.
- Click Convert to CSV.
- Copy into a .csv file or straight into your spreadsheet.
Frequently asked questions
What if objects have different keys?
The header is the union of all keys; missing values become empty cells.
How are nested objects handled?
They are embedded as JSON text in the cell, so no data is lost. Flatten beforehand if you need columns.
Will commas inside values break the CSV?
No — such fields are quoted per the CSV standard.
Is my data uploaded?
No — conversion is local.
