This week, we've released some updates to improve the import/export experience for Microsoft Word and Excel files to and from Google Drive.
Now, when converting a Microsoft Excel file to a Google spreadsheet, you'll be able to import embedded pictures - plus radar and stock charts. When you're exporting to XLSX, charts will be exported as native charts, and your chartsheets will export properly. Additionally, your pivot tables will be fully imported and exported, except for those pivot table features not supported in Google spreadsheets.
When you convert a Microsoft Office file to a Google document, you'll notice that fonts, document background, table borders, and Equations are imported more seamlessly, too.
