Frequently Asked Questions
How do I convert JSON to CSV spreadsheet format?
Paste your JSON array into the input area and the tool converts it to CSV format. Object keys become column headers, and values become row data. The output can be directly imported into Excel, Google Sheets, or any spreadsheet application.
What JSON structure works best for CSV conversion?
An array of flat objects works best: [{"name":"John","age":30}, {"name":"Jane","age":25}]. Nested objects and arrays are flattened or serialized. Consistent keys across objects produce the cleanest CSV output.
Can I open the converted CSV in Excel?
Yes! Copy the CSV output and save it as a .csv file, or paste it directly into Excel. The standard comma-separated format is compatible with Microsoft Excel, Google Sheets, LibreOffice Calc, and all major spreadsheet applications.
