Custom Fonts Helvetica

Hi lherbert501 ,

Your JSON syntax looks correct, but there are a few reasons why Helvetica might not be appearing in your font dropdown.

Most Likely Issue - Font Availability: Helvetica isn't a standard Windows font. Power BI can only use fonts that are installed on your system. Helvetica is typically found on Mac systems, but Windows uses "Arial" as the Helvetica equivalent.

Solutions to try:

Option 1: Use the correct Windows font name Try "Helvetica Neue" if you have it installed, or use Arial:

{
  "name": "Custom Font Theme",
  "visualStyles": {
    "*": {
      "*": {
        "general": [
          {
            "fontFamily": "Arial"
          }
        ]
      }
    }
  }
}

Option 2: Install Helvetica on your system If you have a Helvetica font file (.ttf or .otf), install it on Windows first:

• Right-click the font file → "Install"
• Restart Power BI Desktop
• Then use your theme

Option 3: Try the exact font name Check what the font is actually called in Windows. Sometimes it's "Helvetica LT Std" or similar. You can check this in Windows Font Settings.

Option 4: Use font fallbacks

{
  "fontFamily": "Helvetica, Arial, sans-serif"
}

The theme structure you're using is perfect, so once you have the right font name, it should work. Make sure to restart Power BI after applying the theme.

You can find more details in the Power BI themes documentation.

Hi lherbert501 

I believe you have already installed the font. If that's the case, please check if the attached theme works for you. It seems to be working for me.
