Formatting CSV files in Excel

Formatting CSV files in Excel

As a csv file is a text delimited file it doesn’t contain any formatting. The process of formatting csv files in Excel is a repetitive process which is an ideal candidate for a macro.

You can store macros you need to run on different excel workbooks in your personal workbook. This is a hidden workbook which loads each time you start Excel.

When the csv has loaded , click Developer, Macro and run the macro FormatCSVandAutoFit as shown in the video below.
