Excel 2010 default cell format

Hi –

Is anybody aware of a setting to change all cells to default to date format? This has happened and we can’t figure out how to set it back to normal. So even when a new worksheet in opened it defaults to date format.

Check the XLSTART folder.  If there is a file there, check it out.  If it contains formatting all new workbooks will use that as default.

It can usually be found here: C:Program Files/Microsoft Office/Office14/XLSTART

Sounds like the default template has been changed.
See if this gets you pointed in the right direction.

There were a number of complaints like this some months back. At the time, it was believed that the Normal style was corrupted. Please make sure that the normal style uses the General number format. To check:
1.  On the Home menu, select Cell Styles
2.  Rightclick the Normal style in the resulting dialog, then choose Modify...

You should see a dialog like shown below:

Assuming that style corruption is the root problem, some people have reported that it results after you copy data from one instance of Excel to another. This cause is discussed in a Microsoft Answers forum thread Excel 2010 changes number format after saving
