Generic These settings are necessary for LibreOffice to be usable for everyone and, as such, comply with our design principles.
Advanced These settings aren't necessary for the usability of LibreOffice and don't comply with our design principles.
Contextual These settings are relevant only in special situations and should be presented elsewhere in the UI.
Unnecessary These settings can be gotten rid of as they have been obviated by a change in LibreOffice's behavior/functionality.
New These settings are not currently found in the global sections of the Options dialog but are in fact generic application-wide options.
- These settings are yet to be sorted.




Use this tab page to enter or edit user data. User data is used by templates and Wizards in LibreOffice. For example, the "First name" and "Last name" data fields are used to automatically insert your name as the author of a new document. Some of the user data is included automatically in an internal dictionary so that it is recognized by the spellchecker.

User Data

Year (two digits) Advanced
Defines a date range, within which the system recognizes a two-digit year.

In LibreOffice, years are indicated by four digits, so that the difference between 1/1/99 and 1/1/01 is two years. This Year (two digits) setting allows the user to define the years in which two-digit dates are added to 2000. To illustrate, if you specify a date of 1/1/30 or later, the entry "1/1/20" is recognized as 1/1/2020 instead of 1/1/1920.

Warn when not saving in ODF or default format Advanced
You can choose to get a warning message when you save a document in a format that is not OpenDocument or which you did not set as default format in Load/Save - General in the Options dialog box.

For the latter, it would be best to use a modal dialog both after saving and saving as.

Locale setting Advanced
Specifies the locale setting of the country setting. This influences settings for numbering, currency and units of measure.

The "Default" entry selects the locale setting that is selected for the operating system. A change in this field is immediately applicable. However, some formats that were formatted by default change only if the document is newly loaded
