About >

There are many Apple II files that are of a very specific binary format that can not be directly viewed or edited on other computer platforms. LibreOffice has a extension technology to allow for importing and exporting of non-native files.

Support >

Support for these LibreOffice extensions can be found on the ##apple2 irc channel on the irc.libera.chat server.

June 2026: AppleSoft BASIC Import/Export 1.0 released. AppleWorks GS Word Processor Import 1.0 released.

Applesoft BASIC Import and Export
This extension is only available with Writer documents--a Writer window needs to be open to access them. The default file name filter uses an extensions choice of .bas, .apbas, and .fpbas. The filter selection can be changed to all files.

The Import filters out characters in REM statements that would not be enterable using the Applesoft line editor. When the Applesoft import completes, the resulting new Writer window may behind the current Writer window. The export filter truncates leadeing spaces in REM statements and ensures that line lengths do not exceed 239 characters.

AppleWorks GS Word Processor Import
This extension is only available with Writer documents--a Writer window needs to be open to access them. The default file name filter is .awgswp. The filter selection can be changed to all files.

The import only captures the text in the body (no header/footer). The font styles supported are Bold, Underline, italics, subscript, and superscript. There are about 20 font names that will be attempted to use (these fonts are stored as IDs in the Word Processor files and have to be statically given names). Most modern systems will not show these IIGS fonts (i.e. Geneva) so they will be displayed using some type of substitution by the native system's font manager. The less common Apple IIGS fonts will get converted to Liberation Sans. When the Applesoft import completes, the resulting new Writer window may behind the current Writer window.
