Formula takes a few seconds to populate after the sheet is opened

What could be the root cause for a formula not populating until a few seconds after opening a worksheet?

I built a formula off of a contact cell that references a roster to show an individuals manager but unlike all the other formulas in the sheet, this one takes a few seconds to calculate, it is throwing off my reports as the report shows blank until i go into the worksheet and let it load. Formula is below for reference:

=IFERROR(IF([Assigned To]@row <> "", INDEX({All Pod Detail Range 1}, MATCH([Assigned To]@row, {All Pod Detail Range 2}, 0), 3), ""), "")

hopefully I explained this well enough

Thank you

    How long is your roster and how big are your two ranges that are cross sheet referenced?

  • The two ranges are each roughly 500 rows, 1 is 3 columns, 1 is just 1 column, both within the same range. Within the 500 rows is the roster. Does it have anything to do with using the contact cell as part of a formula? I have multiple other index/matchs on the sheet that work perfectly - or is the range too large? The latter is hard to avoid

    It sounds like you just have a lot going on in the sheet which most certainly causes thing to slow down.


    From the sound of it, your best option is to try to simplify as much as you can. Cell links and cross sheet references definitely put a draw on your speed. A lot of formulas feeding off of each other will, and conditional formatting plays a big roll as well.
