All data declaration for Veda models is done in Excel files. But to visualize models, one MUST use the interface and NOT rely on Excel files. Excel should be used only for the initial and additional data specification. To check the parameter declarations or topology for any particular item, one must use Browse (or Items detail). For example

Browsing model input is necessary for two reasons:
  • You may have a syntax error and some of your declarations may have been ignored, or read differently from what you intended.

  • The declarations for a single item may be spread across several Excel files, and you will see them all in one place in the interface.


  • Browse both presents the actual model data and provides direct access to the input data.

  • Clicking any input cell in the data cube (red circle) provides direct access to specific cells in the excel templates for editing.


The Browser thereby enables the user to view subsets of the assembled data in a cube by selecting the scenario(s), region(s), process(es), commodity(ies), and/or the attribute(s) of interest. It is possible to rearrange the layout of the cube by adding/removing dimensions (columns and rows) to/from the table.
