The export to Excel option has changed where the data is exported as text instead of HTML as it did any version of Project Insight prior to 126.96.36.199. The reason for the change was due to a Microsoft security update that would block any file originating from the internet that was being opened with an Office program. The most significant differences from this change is that the formatting of the export to Excel will be appear different to previous versions since the file will not have any formatting.
The second change is for anyone using the group by feature in their exported reports. When exporting previously, any grouping that was collapsed would export collasped as well and the user would need to Unhide the rows that were collapsed. Now when exporting a report with groupings, the report will automatically show all grouping expanded when export to Excel.
