A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Here is how I've been able to get what I like.
1) Create a book.xltx template with all the styles etc. you use/want and save it to the C:\Program Files\Microsoft Office\Office15\XLSTART\ folder.
2) Under Excel Options (File\Options) General Start up options, uncheck the Show the Start screen when this application starts.
Now whenever Excel opens, I get a new book1 - Excel workbook based on my customized book.xltx template.
As a backup, I also save the template in the C:\Users<username>\Documents\Custom Office Templates\ folder so I can open it with File\New\PERSONAL.
