Excel Recalculates Repeatedly Due To Linked files

Help Something Else
1

Hi @all,

In production, Excel Files With Links Keep recalculating and slow down automation. How can be avoided without code changes??

Thanks!

Hi @MeganQ,

Force excel into manual calculation mode.

open a dummy excel in manual mode using excel application scope, then run all other excel workflow inside the same loop.
Excel calculation is application- level so recalculation is prevented for linked files.

Hi @MeganQ ,

Excel keeps recalculating beacuse linked fomulas auto-refresh. open excel in manual calculation mode and run all workflows inside the same Excel Application Scope-recalculation stops without any code changes.

Hi @MeganQ ,

Open a blank Excel file set to Manual calculation first and keep all Excel work inside the same Excel Application Scope. Excel applies the calculation mode from the first opened workbook, so all linked files opened afterward won’t recalculate and the automation runs faster.

@MeganQ

its a one time setting that you need to do in your excel settings

file → options → advanced formulas → select manual here and also uncheck multi thread

so that no auto calculation is performed when the excel is opened

cheers

Hi @MeganQ

This usually happens because Excel is set to automatic calculation, and linked files force a recalculation every time the file is opened or updated.

Without changing code, you can try:

  • Set Excel calculation to Manual on the production machine
    (Excel → Formulas → Calculation Options → Manual)
  • Disable Update links on open
    (Data → Edit Links → Startup Prompt → Don’t display the alert and don’t update)
  • Make sure linked source files are accessible; broken or slow network links cause repeated recalculation
  • If possible, open Excel once manually, apply these settings, save the file, and reuse it

For files with links and formulas. Make sure you first verify linked file sources and update of required. Then make sure you set the excel to manual mode, either from excel formulas tab and keep manual or use vba.
Or simply keep a dummy excel open in manual mode , after that all excels will get opened in manual mode.
