Batch save and replace multiple files

I have multiple files open using import feature. I converted them all to Mono using macro, but i don’t know how to save them. I once tried to Export > Export as Ogg. But it only exports one file. (I just downloaded Audacity a few minutes ago). How do i get around this problem? Thanks

To export each track as a separate file, use Export Multiple “based on tracks”. See: https://manual.audacityteam.org/man/export_multiple.html
