1. Is this request related to a challenge you're experiencing? Tell me about your story.

When I use drawing tools, such as chart; DALL-E, the output file type data cannot directly extract the URL, which makes it impossible for me to convert it into markdown format data output. At the same time, when these drawing tools are embedded in the workflow, they cannot be used as results in the end node, which is very difficult to use.

2. Additional context or comments

I think file type data can be converted to json to facilitate subsequent operations.

3. Can you help us with this feature?
