How to read a corrupt single line GPX file?

Hi Garmin Forum~

I'm trying to read a corrupt GPX file. A large number of waypoints have been saved into one gpx file. BaseCamp and other GPS softwares couldn't load it, and when I looked at the file in terminal, there are no line breaks. The whole file is a single line. I found here on the forum that TopoFusion can recognize and clean up these types of files, but I'm out in the field with a mac so that won't do me a lot of good. I've attached the corrupted file below. If anyone has any insights, I would be grateful!

Thanks, Ben

Yes TopoFusion did read this .gpx okay. I saved it then imported into Basecamp, and there are 22 waypoints now visible to BC. This is the edited .gpx from TF. Let me know if this works for you!

Not seeing your file. You might need to zip the file first, then attach it.

Hi Seilogramp~

Thanks for the response! Does look like .zip is recognized not .gpx for upload, trying it here:

Eyelet99~ Works like a charm... Thanks for your help!

Looks like TopoFusion is the save-all for old GPS that often corrupt data. I'll look into parallel booting my mac to run Windows for TopoFusion. Saved a good 12hrs of trekking around swamps, so much appreciated!
