    Re: Convert Formula to Macro Functions

    User Defined Functions are always slower than the native Excel functions they try to replace.
    Here's a method I use when I have an huge volume of sluggish formulas that slow down workbook performance, but rarely need updating.
    • Store a copy of the formula(s) someplace in the workbook (I usually put them in a hidden row above the formula range)
    • Convert the slow formula range to values.

    When the formulas need updating, I run a macro that
    • Copies the template formulas into the formula range
    • Re-Calculates the workbook
    • Converts the formula range to values

    I hope that helps.
