In the entry overview, you can click Export in the upper right corner. You will be presented with a form which represents the same settings you were currently viewing: the search query, selected scopes with their parameters, visible fields, sorting, and so on. So when you change nothing and click Export on the bottom, you will get an export file with exactly the entries you were viewing in the entry table.
Of course, you're free to change any setting to define your exported entries. In the lower right corner, you see a live count of the entries that will be exported.
The result of the export will be a CSV file. The default delimiter is semicolon, but you can change it to comma or tab in the export dialog. Every file that is exported from Devisto, can be imported again without any problem.
Below we list the fields that need some special treatment while exporting.
Fields that contain multiple values (like relation or asset fields), will result in multiple columns in the export file. Each column header will be suffixed with an index:
_2 and so on.
Translatable fields will result in separate columns for each language, in the same order as your languages.
Relation fields will output the related ID. Optionally, you can change Export Relations As to Title, which means the title field of the related table will be used (see Title & URL Fields). In fact, this will result in the same values you see in the entry table.
Asset fields will output the asset ID. Optionally, you can change Export Assets As to URL, which means the URLs of the assets will be exported instead.
