This is a tool to convert an exported calender (.ics-file) into a table-formatted data grid, while calculating the hours you worked. I made it because I use iCal / BusyCal for keeping track of worked hours but these apps do not calculate those hours for you.
You can load an .ics-file by dragging and dropping it onto the grid or by choosing Open... from the File-menu. When you load a file, the following tags get processed: DTSTART, DTEND, SUMMARY, LOCATION and DESCRIPTION. The start and end-times are split into two columns and the hours are calculated. Hours are rounded on whole and half hours.
