Hello mpricha,
Welcome to the Forum!
This macro expects row 1 to hold the column headers. The macro reads the file extensions in row 1 starting with column "C". The extensions should include the asterisk, for example: *.xls. You can new extensions as needed without changing the macro code. The macro determines the number of rows with file paths automatically. If a file path does not exist then the message "Path not found" will appear under the extension columns. Copy this code and paste it into a new VBA module in your workbook.
