Currently, when custom formatting is configured in a visualization (e.g., a cross table) and exported to Excel, the formatting is not retained.
Please add a functionality to ensure that the Excel export matches exactly what is displayed inside Spotfire, which would greatly improve the user experience.
Since Spotfire 14.0 LTS, it is possible to export a table visualization (tables, cross tables, summary tables, and graphical tables) preserving layout, styling, and formatting. Simply right click the table visualization and go to Export > Export visualization to Microsoft Excel.
