Frequently asked questions
What JSON shapes are supported?
An array of flat objects works best, as keys become CSV headers. An array of arrays is converted row-by-row. Nested objects or arrays are stored as JSON strings in their cell.
Can I use a semicolon or tab as delimiter?
Yes, choose comma, semicolon or tab. Semicolon is common for European Excel locales.
Is my data private?
Completely. The conversion happens in your browser; nothing is uploaded.
