Hi just uploaded a Word document into Google Docs and it has red dotted underlined text throughout the document. What is this? It does not seem to be indicative of misspellings or grammatical errors.
Probably the document includes Tracked Changes (though if you've never used
Track Changes, the underlines would normally be solid). Go to the Review tab,
find Track Changes, find Accept Changes, and choose "Accept All Changes in
Document."
(When you send someone a document with Tracked Changes in it, it opens
with the changes showing, so that the recipient knows it's been altered
deliberately.)
