Frequently Asked Questions
What if objects have different keys?
The tool uses headers from the first object. Missing values become empty cells.
Can I convert nested arrays?
Yes, but they'll be stringified as JSON in the cell.
Is there a size limit?
No hard limit. Large files may be slower to process.
Is my data secure?
Yes. All processing is browser-based. Nothing is uploaded.
