Cant open .out files with excel

A user at my company cant open a .out file with excel.  Even when manually choosing "open with" navigating to and selecting excel.exe, Excel wont appear in the programs to choose from window as an option.  Attempted go to windows explorer and %appdata% in address to rename the profile excel folder, so when reopening excel it would recreate and work off of a new excel profile folder "in case it was corrupt".  Tried to associate a file type  "in default programs" to force .outs to open with .csv.  Tried to run the office repair tool and restart.  

Reinstalled office.  Still cant open a .out file in excel.  Currently we have to create an excel shortcut on the desktop and actually move the .out into it, so it can be brought up in excel but this is not ideal cause she has many files that would have this to be done for so they can be saved in .csv format.

In 25 years of working with Excel, I've never come across .OUT files...  However, the reason I'm here is to deal with new stuff, so here we go!

According to
 - OUT files are Output files from either Linux compilers (unlikely to be the case here...) or some batch processes.

If it's the latter, I'd suggest that the easiest thing would be to rename these files - a short batch file along the lines of
REN C:\output folder\*.out *.csv
should do the trick.

The last option would be to add a shortcut to Excel to your Send To location, and then use that.
check this (all Windows versions):

After making the changes above, you may need to restart before the new Send To becomes live...

Then, r-click the OUT file, choose Send To, and pick Excel.

Yea, she actually was manually changing the extensions to .csv and that does work fine but she has to do it for a lot of files. Also, I just tested and it does work when adding the excel shortcut to the send to menu but the problem is the same in that she would then have to manually rename and save each doc as a .csv.  I'm hoping to either make it work like normal or a way that doesnt take a lot of manual intervention.

There is a lot of linux btw and financial cycle processing that goes on at my company so that probably is then where the .out files come from.

Doing either the rename *Or* the Send To should workaround this issue - shouldn't need both!

Other option would be to talk to the Linux guys and see if they can rename the file before it gets to her?

Can you post a sample file so we can check the format?

@DanCh99 is correct. This might be a wonderful opportunity for you to use Powershell...

I got it.  After using ccleaner to update registry keys, it works fine now.
