I am working on a project where I take the data from one worksheet, put it in another, clean up the data, calculate the days between steps in the process and then chart it. I've accomplished most of it (still need error trapping and some little tweaks), but now managment wants to be able to pull the data for a user specified date range. Meaning, although the data is for a whole year, they might just want the first six months.
Now I'm not sure what my next step is since I see problems with all three ideas I had :
Change how the data is copied and pasted (Already slow, would this slow it down more?)
Filter the data I have (Filtering based on dates can be...unreliable)
Delete rows based on cell values (I know it can be done but I don't know how to do it)
If someone could give me a push in the right direction, it would be greatly appreciated.
I've attached my spreadsheet with associated macros.
