TDF Tracker offers several options for exporting a report via email. A report can be previewed/emailed from the Report tab - by tapping the "Action" icon in the top right corner of the navigation bar.
The email report itself is an HTML report that includes both a summary and details for the reporting period. It can be copy & pasted from an email into Excel.
TDF Tracker v1.4 and later have the ability to include the report as a CSV attachment - which can also be opened and manipulated in Excel or other programs that can import a CSV file. There are also options (under Settings-->CSV Options) that allow you to change the delimiter and Text Encoding to match your specific needs.
Future updates are planned to further enhance reporting capabilities and options.
