I am receiving chart data in JSON format to my email address and my goal is to convert it to chart/chart img and resend it to my email address.
I have been looking for several methods:
Google App script used for gmail. I failed to find trigger on newly received message.
Email client, that supports adding actions based on scripts to new incoming message trigger. Only one I know about is MS Outlook with VBA scripts, but creating chart image with lack of libraries available in VBA is not very elegant solution.
Open source email client with possibility to alter the code and so directly process data and resend message. The more robust email client, the harder is to change the code to do relatively simple job, I believe.
I really don´t know what kind of solution this simple problem needs.
Thank you in advance.
