Excel Slow? It may be the Google Desktop application causing it.

Has your Excel application slowed down lately? Have you installed the Google Desktop Application?

They may be related. Dick from Daily Dose of Excel reports this article taken from Charles Williams web page.

This report comes from Charles Williams of DecisionModels.com fame. Charles knows a thing or two about performance in Excel.

For the last few weeks I have been trying to find out
why clearing a large range of cells caused Excel to hang on some PCs
but not on others. This does not happen with Excel 97, but does with
Excel 2000, 2002, 2003 and 2007.

It turns out that its not just Clear, but also Delete or
transferring data from a variant to a range, or even just selecting a
large range of cells. The further down the sheet and to the right the
slower it gets. And the more recent the Excel version the slower it

Someone on the newsgroups discovered that, when using VBA, you could
bypass this problem by switching off EnableEvents, and then someone
else discovered that the culprit was Google Desktop Search.

The problem actually turns out to be the Google Desktop Office Com Addin. When you deactivate this you get a miraculous speedup.

With Excel 2007 it is fairly easy to deactivate:
Office Button–>Excel Options–>Addins–>Com Addins and deselect Google Desktop Office Addin

With earlier versions of Excel you have to customise a toolbar and add the Com Addins dialog to it.
View–>Toolbars–>Customise–>Commands tab–>Tools then about
halfway down you will find Com Addins, select and drag to the toolbar
of your choice.
Then you can uncheck Google Desktop Office addin.

If you have multiple versions of Excel installed you only have to do this once.

Presumably this COM addin sets up one or more application-level
events to monitor things like Selection Change and Worksheet change and
then tries to trap the change in order to index it.

If you want to measure this effect you can download a Variant
Benchmark Timer from my website that allows you to run a read and write
benchmark with and without EnableEvents.


This represents an interesting new twist in the Google-Microsoft wars!

Thanks Charles.
