Frequently asked questions
What JSON formats are supported?
The tool supports arrays of objects, nested objects (which are flattened), and simple key-value JSON. Arrays of primitive values are also handled.
Is there a size limit?
The conversion runs entirely in your browser, so there is no upload limit. Very large files (10MB+) may take a few seconds to process.
Does it handle nested JSON?
Yes — nested objects are flattened using dot notation (e.g., address.city becomes a column header). Nested arrays are joined with semicolons.
