This week, Speed up your Spreadsheets – Your Action Required



In recent installment of Customer Service Dashboard post, our reader Salmon asked an interesting question,

I am struggling with data size with my dashboards…so many SQL data pulls and formulas to generate the Dashboard, the entire file is massive and sluggish. Perhaps a few tips from Chandoo Master for all us rookie dashboard designers regarding how to minimize file size and maximize calc speeds. #

Dan l & others chipped in and shared their ideas on speeding up Excel. But the topic is wide & has many solutions. So I am dedicating an entire week to discuss this. Welcome to Speedy Spreadsheet Week.

    Hello Chandoo,

    Nice idea, and nice logo. Love it.

    First of all I deactivate automatic calculations and press F9 when needed for huge spreadsheets.
    I also deactivate automatic save because it can be really long on network drives.

    I would occasionnaly check the performance of integrated function vs operators (like CONCAT or &), but I lack time these days.

    an oldy but a goody: add this string to any recorded macros:
    application.screenupdating = false
    to speed up any macro code you rely on.

    Not a speed-up in the true sense of the world, but use named ranges in any formula. While it may not make the sheet itself quicker it *will* make it quicker to add new formulae and do the inevitable debugging your sheet may require.

    1) Isolate formulae that are repeated and move them to a single cell. Provide reference to the cell in the formulas.
    2) Reduce usage of volatile functions like OFFSET(), RAND(), NOW(), TODAY() etc
    3) Turn off automatic calculations.
