This module provides a way to export Webform submissions as valid Microsoft Excel (.xlsx) files. This offers a more reliable alternative to the built-in exporter which can trigger warnings in newer versions of Excel.
This module provides a Webform submission exporter that can be used to export submissions in the Office Open XML format used by Microsoft Excel.
Webform itself includes a table exporter that can generate .xls files but these trigger warnings in recent Microsoft Excel versions (because they are not real Excel files). So this module is a replacement that produces valid Excel files.
