Create and edit xls and xlsx spreadsheets with OpenOffice Calc online
OpenOffice Excel Online for XLS Spreadsheets is an extension to create, edit and view any Microsoft Excel spreadsheet in xls and xlsx formats. This is a spreadsheet integrated with our file manager to manage only XLS file types with this desktop application

The main features of OpenOffice Excel are:
- Wizards that guide you through choosing and using a full range of advanced spreadsheet functions

- Flexible cell formatting options: rotating content, templates, backgrounds, borders and many more

- Ability to cross and summarize

- Creation of formulas using words

- The Smart Sum button inserts a sum function or a subtotal automatically, depending on the context

- Range of extension repository templates for out-of-the-box spreadsheet solutions

- Advanced styles and formatting

- Save your spreadsheets in OpenDocument format, the new international standard for office documents. But you are free to use your old Microsoft Excel spreadsheets, or save your work in Excel format or use Portable Document Format (.pdf)

- Integrated with a file manager to save, upload and download xls files

This extension uses the platform. It is an integration with an Open Office Linux desktop application. Concretely, it is a desktop application working through our OffiDocs API. It is available for free online users, but it also allows integration with premium users and on-premises OffiDocs deployments where OffiDocs OpenOffice Excel is installed.
