Veelgestelde vragen
›What JSON shape is required?
A JSON array of flat objects, e.g. [{"name":"Ada","age":30},{"name":"Linus","age":33}]. Nested objects are flattened or stringified.
›Are nested objects supported?
Yes — nested objects are stringified into a single cell. For deep nesting, flatten your data first.
›Is my JSON uploaded?
No — conversion runs entirely in your browser, even the .xlsx generation.
›Can I customise columns?
Currently we use the first row's keys to determine columns. For custom column mapping, pre-process your JSON first.
›Is the converter free?
Yes — fully free, no signup.
