How do I create a new workbook in Excel 2010 format?

I'm currently using Excel 2010 but when I create a new workbook with Control-N or with VBA (Workbooks.Add), I get a 2003 style book that opens in Compatibility mode with only 256 columns. How do I create one with the standard 1,048,576 rows and 16,384 columns in Excel 2007 and 2010? I tried saving the new workbook as an .XLSM but that didn't help.

Better still, since I've already populated 4 sheets with a lot of data in a new workbook before realizing that it was 2003 style, is there a way to convert those existing sheets to 16,384 columns?

I have no idea how I created my first Excel 2010 workbook in the first place.

This is very perplexing to me.

Thanks,
John

You should be able to convert the existing ones by using File, Save As and selecting the .xlsx ending from the pull down file type menu as shown in the attached file, Excel 2010 Save As.

Additionally, you should be able to set the default file type back to the new version by going to File, Options, Save and choosing the Excel Workbook type, as shown in Excel 2010 Save Options.

What is your current default "Save As" file type?

Go to FileOptionsSave

Check the current setting in the drop-down list for Save files in this format.

If it set to .xls or another type, change it to .xlsx.

tqfdotus, you actually posted first but I want to split the points since ThinkSpaceSolutions' boldface Go to File > Options > Save jumped out at me first.

Thank you both!

No worries.  Experts should be more worried about providing solutions and relative information rather than focusing on points anyways (imo).  Glad I could help nonetheless.
