# Um að umbreyta Microsoft Office skjalagerðum

LibreOffice can automatically open Microsoft Office 97/2000/XP documents. However, some layout features and formatting attributes in more complex Microsoft Office documents are handled differently in LibreOffice or are unsupported. As a result, converted files require some degree of manual reformatting. The amount of reformatting that can be expected is proportional to the complexity of the structure and formatting of the source document. LibreOffice cannot run Visual Basic Scripts, but can load them for you to analyze.

The most recent versions of LibreOffice can load and save the Microsoft Office Open XML document formats with the extensions docx, xlsx, and pptx. The same versions can also run some Excel Visual Basic scripts, if you enable this feature at LibreOffice - Preferences Tools - Options - Load/Save - VBA Properties.

The following lists provide a general overview of Microsoft Office features that may cause conversion challenges. These will not affect your ability to use or work with the content of the converted document.

## Microsoft Word

1. Sjálfvirk form

2. Endurskoðunarmerki

3. OLE hlutir

4. Certain controls and Microsoft Office form fields

5. Atriðaskrár

6. Tables, frames, and multi-column formatting

7. Hyperlinks and bookmarks

8. Microsoft WordArt myndir

9. Animated characters/text

## Microsoft PowerPoint

1. Sjálfvirk form

2. Tab, line, and paragraph spacing

3. Master background graphics

4. Hópaðir hlutir

5. Certain multimedia effects

## Microsoft Excel

1. Sjálfvirk form

2. OLE hlutir

3. Certain controls and Microsoft Office form fields

4. Veltitöflur

5. Nýjar gerðir grafa

6. Skilyrt forsníðing

7. Some functions/formulas (see below)

One example of differences between Calc and Excel is the handling of boolean values. Enter TRUE to cells A1 and A2.

- In Calc, the formula =A1+A2 returns the value 2, and the formula =SUM(A1;A2) returns 2.

- In Excel, the formula =A1+A2 returns 2, but the formula =SUM(A1,A2) returns 0.
