Hi Angela. I would look at location #74 and 75 to see if there is something strange in the data (unescaped apostrophe, ampersand, backslash, or other reserved characters.)
I’d also break the list into two parts. Try locations 101-200 and see if that imports correctly. If it does, then it points to a problem with the data itself.
200 locations isn’t a lot to cause a timeout, so I would look at the data first.
