Frequently asked questions

What JSON structures work?

An array of objects (one row each), an array of arrays (rows and columns), or an object whose values are arrays (one sheet each). A single object becomes one row.

What happens to nested objects?

They're flattened into dotted column names like address.city. Arrays inside a row are joined with commas.

Is my data uploaded?

No. The conversion runs in your browser with the open-source SheetJS library, so spreadsheets with customer or financial data stay on your device.
