Designed a userform that converts dimension formats, i.e. information from tabular format to list (or flat) format, and viceversa. Some options include preserving formatting or not, as well as including blank cells or not.

Form is here:Dim changer userform

Excel file with embedded form and a macro to make the form pop up is here:Dim_changer
