EDL is the earliest version of a time-line, before the time-line even existed.
You need to identify whether the timecodes are matching between excel sheet and media file?
Then there is the accuracy of the media file name – if that doesn’t match, you’ll need to “force” a match on relinking the files to time-line.
Fastest way around this might be to set up new project -> import edl -> link clips to media – copy linked time-line across into your master project.
But first, you have to ensure that the timecodes are a match.
The next fun thing, is whether your client have given you what they want to keep (In/Out points)?
Or, as some do, only tell you what they want you to cut out…
