There is an AI program that claims to do this.
I can’t vouch for this one.
Their Denoise program is wonderful but takes time and considerable computing power on each photo.
You can download their programs for a month’s and they are sometimes on special.
Alternatively save the jpegs and it there’s a need to work on them, save them as an 8-bit TIF, so editing doesn’t degrade on each save, as jpegs do.
Don't think that would work, MaryBeth. I just tried opening a jpg in Pshop and saving it as a DNG. Not an option. You would not be adding to the detail or other data even if it were possible.
When you say "data loss problem," what exactly is it that you mean? One can save jpegs at 100%, e.g., no content loss. Or save them as PDFs, which would also save without content loss. The question you need to ask is how were the jpegs originally saved, with or without compression. JPEGS are the least volume in your storage devices also, so it would seem best to simply save them with no compression loss. Depending of course on the size of storage drive.....and your backup storage drive.

Has anyone done this: changed from jpeg to camera raw or dng format? Can this be done to batches of photos? I'm very interested in doing so because of the data loss problem with jpegs; we are archiving a ton of photos right now.
