Save email attachment in sharepoint, OCR the attachment if its an image, update a column on the file

Hi there,


I was hoping someone might be able to point me in the right direction for a task i'm trying to create in Flow.


We would like to scan images to an email address

When an email is received, Flow should save the attached image in Sharepoint

Flow should then OCR the image and find a specific string of text and numbers after it i.e. "Invoice: 99999999"

Flow should then alter the file saved earlier to add the returned string to a specific column i.e. "Invoice No".


I can get Flow to create the file from one of the templates that i've modified slightly, however the pieces i'm missing are 1) letting the OCR (Computer Vision) know the location of the image to scan, 2) searching for the specific string of text and storing it in a variable, 3) getting the file from earlier, 4) updating the file from earlier with the text returned from the OCR step.


If anyone could point me in the right direction for the steps i believe i am missing, or perhaps a better flow entirely to complete the task that would be fantastic!


If there are any more details that would be useful to know please shout up and i'll gladly provide what i can.


Many thanks in advance!

Hi @callum_williams


Could you please expalin more about the OCR that you mentioned.?

Could you please share a screenshot of your flow and share more details about your trouble when achieve your requirement so we would try to provide a proper workaround for you.


Best regards,


Hi Alice,


Here is a link to the Azure Computer Vision app:, you create it as a resource in Azure and then use the keys to link Flow to it.


I've got a screenshot of the entire flow but its quite large so here's a link:


The error happens at the "Optical Character Recognition (OCR) to Text" step,


Here is the full image code:
