Frequently Asked Questions
Does it handle nested JSON?
Yes, nested objects are flattened using dot notation. For example, a field like {"address": {"city": "London"}} becomes an "address.city" column in the CSV output.
What JSON structure is required?
Your JSON should be an array of objects (e.g., [{...}, {...}]). Each object becomes a row, and the union of all keys becomes the column headers.
Can I open the CSV in Excel?
Yes. The downloaded CSV file is UTF-8 encoded and compatible with Microsoft Excel, Google Sheets, LibreOffice Calc, and all other standard spreadsheet tools.
Is there a size limit on the JSON data?
There is no hard size limit, but very large JSON files (50MB+) may slow down your browser since all processing happens client-side. For large datasets, consider splitting the data first.
