There are different ways of exporting data with Skrooge depending on what you intend to do.
Using the menu → , a CSV, QIF, JSON, Kmymoney, Sqlite or WML file will be created, containing all operations in the current document. This is the option to choose if you need to export your data to another application.
All tables in Skrooge can be exported, either in CSV, HTML, ODT, PDF, SVG or TXT format.
This works wherever a table is displayed, so you can use it to export whatever tabular information you need.
Skrooge allows you exporting a graph, either in PDF, SVG or just any image format supported by KDE (PNG, JPG, GIF, TIFF...). You can do so by right-clicking on the graph, and choosing the option.
