Download button in View formatting JSON

[Jesper Würtz]

Hi,

Im create a view in a document library to give an overview of the files with a description.

On that view I would like a download button, to download the files directly.

On known file formats link JPG i just opens the file and on unknown formats link EPS it dowloads the file.

The code looks like this:

 "elmType": "button",
                  "style": {
                    "background-color": "#6eb556",
                    "color": "white",
                    "font-weight": "bold",
                    "font-size": "1rem",
                    "float": "right",
                    "margin-right": "150px"
                  },
                  "customRowAction": {
                    "action": "Download"
                  },
                  "txtContent": "Download",
                  "attributes": {
                    "class": "sp-row-button"

Is there a way to force it always to download the file?

@Jesper Würtz Have you found a solution to this? I also need a button in a sharepoint document library that allows the user to download documents.

According to this article it seems that only 

• defaultClick
• share
• delete
• editProps
• executeFlow

are valid option for "customRowAction.

I have a script for a download button that works:

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/column-formatting.schema.json",
  "elmType": "button",
  "style": {
    "flex-direction": "column",
    "width": "80px",
    "border": "none",
    "border-radius": "3px",
    "margin": "10px 0"
  },
  "attributes": {
    "class": "ms-bgColor-themePrimary"
  },
  "children": [
    {
      "elmType": "a",
      "txtContent": "Download",
      "style": {
        "color": "white",
        "text-decoration": "none",
        "padding": "12px 0px 12px 0px"
      },
      "attributes": {
        "target": "_blank",
        "href": "= @currentWeb + '/_layouts/15/download.aspx?UniqueId=' + [$UniqueId]"
      }
    }
  ]
}

How to:

1. Create a single line column named f.ex. "Download"
2. Add the json script in format column
