TechCurmudgeon writes with a look at how well Google Docs and Microsoft Word Online are at dealing with documents that start (or are exported) in Open Document Format. Does using proprietary document formats make any more sense than buying a coffee maker that uses only one type of coffee, or an ebook you can only read on one device, or a nail that you can only hit with one type of hammer? Why do we use document formats that lock us into only one specific piece of software? Why are we limiting ourselves to only one type of tool? "Control of a format or distribution channel can make it harder to use a competitive solution. That's one problem of proprietary formats: a switch costs you time and/or money. You don't want to buy a new coffee maker to try different coffee, a new e-reader to read a different book, or new software to edit a new document. Open formats or distribution channels make it easier for people to choose a different solution. ... Fortunately, Google re-enabled support for ODF in December 2014. That means you can leverage the collaborative capabilities of Google Docs, Sheets, and Slides, then export your completed work to a file in an open, non-proprietary format." Spoiler alert: On balance, both Google Docs and Word Online handle ODT files reasonably well.
