How To Format Subheadings and Columns and lists in excel 

How do i add the heading please

I've done a column setup with a file from an app that ended and required that you download and save your info into a .csv file. When I save the file with the changes it doesn't save any of the formats, ie; column spacing, bolding, font size, etc. When I open the file back up it is back to where it started, however, if I add new information to the file it will save that information. How do you keep the format?

Thank you so much you explained everything perfectly making it easy to understand I wish you could make more videos ☺️

Best yet!!!!😊

this is not a proper excel table though.

Thank you 😊
