You can open and save data in the dBASE file format (*.dbf file extension) in LibreOffice Base or a spreadsheet. In LibreOffice Base, a dBASE database is a folder that contains files with the .dbf file extension. Each file corresponds to a table in the database. Formulas and formatting are lost when you open and save a dBASE file from LibreOffice.
Choose File - Open.
Locate the *.dbf file that you want to import.
The Import dBASE files dialogue opens.
The dBASE file opens as a new Calc spreadsheet.
If you want to save the spreadsheet as a dBASE file, do not alter or delete the first row in the imported file. This row contains information that is required by a dBASE database.
A LibreOffice Base database table is actually a link to an existing database.
In the File name box of the Save As dialogue, enter a name for the database.
In the Database type box of the Database Properties dialogue, select "dBASE".
Locate the directory that contains the dBASE file, and click OK.
Choose File - Save As.
In the File format box, select "dBASE file".
In the File name box, type a name for the dBASE file.
Only the data on the current sheet is exported.
