No. We recommend switching your file to *.xlsx format before uploading to SpreadsheetWEB, as VBA codes and macros are not supported. Most macro-enabled workbooks use VBA for user interface purposes. SpreadsheetWEB comes with numerous browser-based user interface features that you can use, and create similar user interface features in your web applications. If your macros contain business logic and calculations, we can work with you to rewrite the business logic using native spreadsheet functions, or custom actions.
