You can create CSV templates using Microsoft Office or LibreOffice.

Bands in CSV template should be horizontally oriented, so the suitable named region will grow downward. Also, bands should belong to the first level of data, i.e. be the children of the Root band. In all other respects, the same principles as for XLS/XLSX templates should be used.

Inline editor

CSV templates support inline editing. You can edit the template directly in the Template editor window and see the changes without having to re-upload the template file.
