Hello,

Even when it does not contain any macros, is there a downside to saving an Excel (2010) file as a macro-enabled (.xlsm) file versus a typical (.xlsx) file?

Thanks

Hello Steve,

.xlsm is only required if the file contains macros. If it doesn't, .xlsx will do nicely.

If the file does not have any macros, then saving as .xlsm won't do much harm, although some corporate firewalls or web sites may not allow up/download of .xlsm files to safeguard against malicious intent (VBA can contain bad/destructive/viral code)

Not for points...

I would just add if you are using any XLM functions (Excel 4 macro functions) you'll have to save as .XLSM.

Depending on your security settings, it adds one or more steps for your users to get a file opened and "enabled".

They may be prompted to "Enable content" before they can work in the file.

Additionally, Excel 2010 tracks the source of the file as well.  So, they may get a fairly "scary" (red text and background colors) warning telling them that the file came from an unknown or internet source prompting them to click a link to review the content and then to select "Edit anyway", before they can "enable content".

So, if you do not need the Macro enabled workbook and your file(s) are for users other than yourself, don't use XLSM until you actually need to include code in your file.

FWIW, the warnings about enabling content only come up if a file actually contains macros. If it only has the .xlsm extension, but no actual macro code in the macro project, then there will be no warnings, since there are no macros. But if you even have an empty sub with no "real" code like ...

sub DoNothing()
end sub

Open in new window

... then the macro warnings will pop up upon opening the file.

Thanks, Steve.

I don't often use chat speak or txt abbreviations, and I assume you don't either. Sorry if I caught you unaware.

Here's a low-level intro http://www.pcworld.com/article/153504/fwiw_the_origins_of_net_shorthand.html

If you really want to get into it, take the deep dive with

I guess with voice recognition it will be much harder to use the acronyms than the full words, which kind of defies the intention of the chat speak acronym. Or can you use shortcuts to certain phrases with Dragon NS?

cheers, teylyn
