Pls change this line to your folder path  as neeed - or remove it altogether to get flexibility as to what folder to select.

strDefaultFolder = "C:\temp"

Your macro is working fine but it is saving in sheet 1 for all the csv files...

Where if we have 2 csv file having 2 sheets then my excel macro should put them into two sheets with their name ...
is this possible ....

If you pick No on the second message
"Extract all data to a single sheet (Yes)," & vbNewLine & "or a target file sheet for each source sheet (No)"
Then you will get a single sheet for each csv file
