Rows are ordered by key (the underlying map is sorted); use the 2-D array mode of “JSON array to Excel” if you need the original order.

Frequently asked questions

Why are rows in key order?

The writer uses a sorted map internally, so keys are ordered automatically; the JSON literal order is not preserved.

Which value types work?

Numbers, booleans and text all work and become the matching cell type; nested objects/arrays are serialised to JSON text.

Can it write several sheets?

One call writes one sheet, named by the worksheet field (Sheet1 when left blank).
