You can open a document saved in another format by using the following procedure:
Choose File - Open.
Select a format from the Files of type list box.
Select a file name and click Open.
If you always want the file dialogue boxes to show another format by default, choose - Load/Save - General and select that format as Default file format.
Open the wizard, which guides you through the operation, to copy and convert all documents from Microsoft Word, Microsoft Excel or Microsoft PowerPoint into OpenDocument file format documents. You can select a source and target directory, specify whether to convert documents and/or templates, and more besides.
