I need to read a very long .txt file, add , delete or modify some rows and then save the resulting file as other .txt file The data in the original file looks like this: <empty row> somedata1 somedata2 somedata3 <empty row> somedata1 somedata2 somedata3 somedata4 somedata5 <empty row> ......and so on. The second file : <empty row> newdata1 newdata2 somedata1 modified _data2 somedata3 <empty row> newdata1 newdata2 somedata1 modified_data2 somedata3 somedata4 somedata5 <empty row> .....and so on I managed to do an VBS script that opens a series of excel files runs a VBA macro and then closes the excels. Problem is, because of the many rows in the txt file, it's going sooooooo slowly and it will be nice not to install MsOffice or .NET Framework just to do this ; and after all why use VBA & Excel when I am almost sure VBS can handle the problem just fine. Any ideeas ? Thanks
