Expansion and interpolation of dated dated

I have dated productivity data that I need to evaluate after the dated data columns are expanded to include all dated data, inclusively, followed by interpolation of productivity data for off working...

    Nope -- I managed to take all your blank dates and develop numbers using TREND...but the results are pretty clearly not what you want. I do think they're an accurate TREND line, but because your overall trend in the productivity numbers is upward over the two years in questions, that general upward trend is what the TREND produced numbers show....increasing by approximately 1/1000th with each new entry. That is NOT an interpolation, however, between the last worked day and the next worked day.

     

    It might be possible to use TREND on a monthly basis, say , for work days missed during any given month....but with over two years of data, that general trend is too general to be meaningful in the granularity of specific weekends.

     

    was an interesting exercise, but didn't produce the outcome you wanted.

     

    Let me add one new function to that series I gave you earlier as functions you might want to study and try: OFFSET.

     

    And you asked about coming back and posting. First, it's entirely possible that somebody far more expert than I might pick up this thread. But if not, after you've continued a few other things on your own, you might come back and start a new thread. It wouldn't be bad to mention a link to this thread, just to keep people from going down blind alleys.
