Frequently Asked Questions
Can I convert nested JSON to CSV?
Yes, JSON Nova automatically flattens nested objects so they display correctly in spreadsheet applications like Excel or Google Sheets.
What is the limit for JSON size?
The limit is based on your browser's memory. Since it's client-side, we can handle multi-megabyte files smoothly using web workers.
Does it handle JSON arrays?
Yes, JSON arrays are converted to CSV rows automatically. Each array element becomes a row in the resulting CSV file.
Can I download the CSV file?
Yes, after conversion you can download the CSV file directly or copy it to your clipboard for use in Excel, Google Sheets, or other tools.
How does it handle special characters?
JSON Nova properly escapes special characters like commas, quotes, and newlines to ensure CSV compatibility with all spreadsheet applications.
Can I convert CSV back to JSON?
Currently, JSON Nova focuses on JSON to CSV conversion. CSV to JSON conversion is planned for a future release.
Does it preserve data types?
CSV is a text format, so all values are converted to strings. However, numbers and booleans are formatted correctly for spreadsheet applications.
Is the conversion reversible?
While you can manually convert CSV back to JSON, some information (like nested structures) may be lost in the flattening process.
