How to Import and Export GPX, KML, and CSV on iPhone

TL;DR

MGRS GPS does full GPX import/export for waypoints and tracks, plus KML and CSV, and opens GPX files shared from other apps — so your data moves freely between planning tools and the field.

Steps

To bring data in, import a GPX, KML, or CSV file — or open a GPX shared from another app.
Review the imported waypoints and tracks on the map.
To send data out, export as GPX, KML, or CSV.
Share the file with teammates or planning tools.

Why it works this way

Your grid app shouldn’t be a dead end for your data. Full GPX support means waypoints and tracks move cleanly between MGRS GPS and the planning tools, mapping software, and teammates you work with — and KML and CSV cover the other formats you’ll meet. Being able to open GPX shared from other apps closes the loop from plan to field.

Tips & edge cases

GPX is the best round-trip format — it carries both waypoints and tracks.
CSV suits spreadsheets of coordinates; KML suits Google Earth workflows.
Open shared GPX to load a route someone planned for you.
