Export option with file format capable of including images

Require an export option to retrieve images and embed in the file with records as part of the exported file.
Cannot currently achieve this with the current txt,csv,json flat files.

Including URL and opening in google sheets isn't an acceptable option of providing files/images to clients. Google sheets will only display the image for the url, not embed it in the file.

I'm currently forced to export records to excel and run vba code to extract and embed the images in adjacent cells. Not an easy task to setup because Knack images are hosted on Amazon AWS S3 which has redirection in place which in turn is prone to clobbering vba calls.
