The exported *.csv / *.txt / *.html files can be opened with MS-Excel, text editors or internet browsers...If you have data in a datatable (e.g. MS-Excel), you can also save those also as *.csv file and import them into the Household Accounting Book.

In general, Household Accounting Book is able to import different files in which entries are delimited by Comma, Semicolon or Tab...specifically *.csv or *.txt files. To import a file select the option "Import file..." in the Import / Restore dialog and select your file path by clicking "...".

Click the Import button...the "Import file..." window will open.
