Hi everyone

I think I have confused myself into a haze.

I have a flow that is triggered from Power apps, but getting data from Sharepoint. Power apps is just telling Power automate which single record to get from Sharepoint. The flow is producing a pdf which it emails to myself. So that part is fine. But I'm not quite sure what I have to do to the data coming from Signature column which is a multiline text. Which is in this format: "data&colon;image/png;base64,iVBORw0KGgoAA......

Any help would be much appreciated.

Hi @Corissandageri ,

It's a dataurl.

https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URLs

Simply put, it converts the binary contents into a base64 string and it adds a header at the beginning.

If you want to convert the dataurl to file content, please try the datauritobinary function in flow.

I tried to use the dynamic content from Sharepoint GetFile
dataUriToBinary(outputs('Get_item')?['body/PSignature'])
But that didn't work

PSignature is my Signature column in Sharepoint

Hi @Corissandageri ,

Please try this:

dataUriToBinary(replace(outputs('Get_item')?['body/PSignature'],'"',''))

Hi @Corissandageri ,

Thanks for your screenshots.

We don't need to convert it from datauri to binary if you use it in html text.

You can use the datauri string directly in <img> label instead of using datauritobinary function.

Hope it helps.
