Edit one thing. Break nothing.
Office files are full of things a phone app might not understand. Most apps quietly drop them when they save. 1B Docs rewrites only what you changed and copies the rest back exactly as it was.

The same goes for documents and presentations: an untouched paragraph, table or slide is written back from the original, so a .xlsm stays a .xlsm and a .pptm keeps its macros.

Measured in our own tests on a collection of 1,367 real Word documents (the one that failed was a damaged file). Very complex documents can still look slightly different from Word.
