Storing string attribute as blob

I have a string I need to store as an attribute, but it’s more than 1023 characters.
I attempted to store it as a blob having a workflow using the “encodeBase64” helper, and set the Attribute Content Type to text/csv, and it appeared to have stored it.

How can I show this string in a dashboard?


To display a blob attribute in a dashboard that is text (rather than an image) you will likely need to use the Custom HTML Block with some JavaScript to decode the Blob data.

Thank you,
