Dataset generator FAQ

Can I generate multiple sheets in XLSX?

Yes, XLSX mode supports sheet count controls within configured limits.

Why does XLSX mode show Download instead of Generate text?

XLSX output is file-based and downloads directly rather than rendering text in the result panel.

Can I still control columns and types for XLSX?

Yes, field and column configuration controls shape generated workbook content.
