Group lines together with dates and time

[paulfink]

hi guys,

need a hand with figuring out how to fix my table.

i got an excel in with thousands of lines of data detailing timings but the way its formatting is messing up my report.

its structured like this:

Project - Date - Time 

the date column has listed out every date (its just how the system works) so if there are dates from 01/02/2022 to 10/02/2022 then there will be 10 different lines which is a big problem.

how can i make it so that these lines will group up and be structured like this:

Project - Start - End - Total Time.

any ideas?

There's probably quite a few ways you could do this, one would be to use Power Query to Group By and add a column for Min Date, and Max Date and rename those as start and end date for the project.

@AllisonKennedy this has partly worked, however, i didn't mention that there could be multiples of the same project against different times in the year. 

could you still do this?

@paulfink  In that case you may need to try something a bit more complex, find the previous date for each project and if there's a gap, then flag it as a start date, if not, check if it's an end date and flag that, then add an index or a count and then group by?

Or you could find this in DAX using variables and MAXX function. Does that make enough sense or do you need more help?
