What started as a simple
text editor and later became am office suite is actually becoming a
very comprehensive set of tools for the daily office work.
LibreOffice is most likely
the only application that can open almost any office file format in
the world. Legacy and modern - it doesn't matter LibreOffice can
handle them. Even some legacy file formats from older versions of
Microsoft Office that can't be recognized by supported versions of
Microsoft Office can be opened and converted with LibreOffice. Its a
well known fact that some corrupted files from legacy Microsoft
Office versions can only be opened with LibreOffice. I'm just
mentioning a few file formats here: Lotus Word Pro, MS Works,
WordPerfect and Cores Draw. Also older versions of office files from
outdated Mac computers like Microsoft Word for Mac, Write Now,
MacWrite Pro and AppleWorks is now accessible.
Besides that LibreOffice
is constantly improving the Microsoft OOXML Import and Export filters
as well as for the Microsoft Office binary file formats and the RTF
format.
With LibreOffice you can
store PDF-files and even embed the original text document or
spreadsheet within the PDF. This makes it possible to do later edits
of the file directly by loading it into LibreOffice. But there is
more that. With the drawing application you can open any PDF-file
that is stored without encryption. You can even edit the content and
you can merge and split the document as you like. Hereby LibreOffice
can replace some of the separate tools that is often used to do these
tasks.
With the spreadsheet
application Calc you can import CSV files and even arbitrary XML
files into a spreadsheet.
LibreOffice runs on almost
any thinkable platform ans operating system and its free. Free as in
free beer and as in free speech. you can download it from here: https://www.libreoffice.org/download/ .
