SharePoint Online - Generate an icon via Column Formatting?

Question

I have a list in SPO with a Choice column (Video, Word, PDF). I would like to display an icon in a column called FileType.

I have tried to customize the JSON of the FileType Column but it just shows the text.

Any ideas?

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
  "elmType": "div",
  "style": {
    "box-sizing": "border-box",
    "padding": "0 2px",
    "overflow": "hidden",
    "text-overflow": "ellipsis"
  },
  "attributes": {
    "class": "sp-css-backgroundColor-BgLightGray sp-field-fontSizeSmall sp-css-color-LightGrayFont"
  },
  "txtContent": "=if([$FileType] == 'Video', 'MSNVideos', if([$FileType] == 'Word', 'WordDocument', if([$FileType] == 'PDF', 'PDF','')))"
}

Answer 1

Try using this JSON for your column JSON formatting:

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
  "elmType": "div",
  "attributes": {
    "iconName": "=if([$FileType] == 'PDF', 'PDF', if([$FileType] == 'Video', 'MSNVideos', if([$FileType] == 'Word', 'WordDocument','')))"
  },
  "style": {
    "font-size": "24px",
    "color": "black"
  }
}

Where FileType is internal name of your SharePoint list choice column. You can get the exact internal name of your SharePoint list column by following this article: How to find the Internal name of columns in SharePoint Online?
