Why can't you upload newer versions of excel spread sheets?Asked by colorado4hfoundation on May 10, 2016 at 03:12 PM
When I try to upload a newer excel spreadsheet file I get and error message. The message says only xls formats are accepted
If you need to allow upload of a specific file type, it should be added in the Extensions from Form Builder.
In case your issue is not related to upload field, let us know where you are trying to upload the Excel file and we will look at it.
