How to apply a custom theme to the dashboard from another Power BI dashboard theme

In Power BI, applying a custom theme to a dashboard involves creating or importing a JSON theme file and applying it to your report or dashboard. However, directly applying a theme from one dashboard to another within Power BI Service is not directly supported. Instead, you would typically export the theme from one report and then import it into another report. Here's how you can do it:

1. Export Theme from the Source Dashboard:

   • 1) Open the Power BI report or dashboard containing the theme you want to export.
   • 2) Go to the "View" tab in the Power BI Desktop.
   • 3) Click on "Themes" and then select "Switch Theme" > "Current file."
   • This will open the "Themes" pane. Click on "Export theme."
   • 4) Save the exported JSON theme file to your computer.

2. Import Theme into the Target Dashboard:

   • 1) Open the Power BI report or dashboard where you want to apply the custom theme.
   • 2) Go to the "View" tab in the Power BI Desktop.
   • 3) Click on "Themes" and then select "Switch Theme" > "Current file."
   • This will open the "Themes" pane. Click on "Import theme."
   • 4) Select the JSON theme file you exported from the source dashboard.
   • Power BI will apply the custom theme to the current report or dashboard.

Alternatively, if you want to apply the same theme across multiple reports or dashboards within Power BI Service, you can follow these steps:

1. Export Theme from the Source Dashboard:

   • 1) Open the Power BI report or dashboard containing the theme you want to export.
   • 2) Go to the "File" menu and select "Options and settings" > "Options."
   • 3) In the Options dialog, go to the "Current file" tab.
   • 4) Click on "Export theme" and save the JSON theme file to your computer.

2. Apply Theme in the Target Dashboard:

   • 1) Open the Power BI report or dashboard where you want to apply the custom theme.
   • 2) Go to the "File" menu and select "Options and settings" > "Options."
   • 3) In the Options dialog, go to the "Current file" tab.
   • 4) Click on "Import theme" and select the JSON theme file you exported from the source dashboard.
   • Power BI will apply the custom theme to the current report or dashboard.

By following these steps, you can apply a custom theme from one Power BI dashboard to another either within Power BI Desktop or Power BI Service.
