Migrated notes / image file names with whitespaces won't load

What I’m trying to do

Ive migrated my Evernote notebooks to Obsidian and I’m now seeing that Obsidian won’t process any of the images because all the file names contain whitespaces and need %20 substituted for white spaces. Is there a simple or automated way to replace the file name whitespace’s with %20 ? How are others dealing with this across a large set of notes? All my notebooks are essentially unusable without the images and there too many notes to do this manually.
