I know nothing in maacro and codes but interested to use someones sweat,

i got a macro from one of the groups and i use for extracting data from many excel workbooks containing only one worksheet, (inspection request with typical data). here, to extract data required manual intervention to open the folder and selecting files. i need macro to select those files from a given folder without any manual intervention. if someone

thanks in advance
