Linking a specific OneNote page to a Sharepoint List

Use a Multiline Text Column + JSON Formatting

• Create a Multiline Text Column instead of Using Hyperlink Column

  • Go to your list or library settings.
  • Add a new column > choose Multiple lines of text.
  • This column type supports much longer values than the Hyperlink field.
  • If using a document library:
    • In Advanced Settings, set “Allow unlimited length in document libraries” = Yes.
  • If using a list:
    • Multiline text already supports unlimited length.

• Apply JSON Column Formatting

Use JSON formatting to render the text as a clickable link:

• Hover over the column header you just created.
• Click the down arrow > Column settings > Format this column.
• A panel opens on the right side.
• In the formatting panel, click Advanced mode.
• Paste this JSON code:

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
  "elmType": "a",
  "style": {
    "color": "#0078d4",
    "font-weight": "bold"
  },
  "attributes": {
    "target": "_blank",
    "href": "=@currentField"
  },
  "txtContent": "Open OneNote Page"
}

• Click Save.
