Google is launching a new version of its Sheets spreadsheet site today that it says is faster, more powerful, and can work offline. With the addition of offline mode, Google now has a much more formidable competitor against productivity giants like Microsoft Office. Its three main tools — Docs, Slides, and Sheets — all work offline now, allowing travelers to rely on Googles sites to have their files ready and editable whenever theyre needed. Alongside adding in offline mode, Google says that the new Sheets has been rebuilt from the ground up to make it much faster.
