Hyperlink – Data Moving

Hello TechRepublic!
The data I have hyperlinked to my excel spreadsheet has been moved to another server source (i.e. from D:\ to L:\) – therefore the links no longer work.
Does anyone know a quick way to change ALL the links to the new server rather than individually editing the hyperlinks? Any suggestions are welcome as I have over 250 hyperlinks to change!!!
Look forward to hearing from you. Thanks
