Hi there -

Thanks for this awesome library! By chance, is there functionality here to convert a .msg file's contents to JSON?

Hi @curldapps and thanks for your support :)

No there is currently no such feature.
What is your need exactly ? The content of a .msg file may take many shapes. How exactly would you expect the JSON to be structured ?

Thanks for the reply!

I built a utility that processes the contents of emails and one component of that is named entity recognition on the body and headers. To feed that named entity recognition model with data it can digest, I use a utility that converts the standard EML mime type emails to JSON and then perform my own processing from there as JSON is much easier to work with.

If I could find a library that could take a .msg email file and create a JSON object something like the following, it would be a lifesaver:

{ 
    headers : {header1: "<value>", header2: "<value>" ...},
    bodyText: "<body text of email here",
    date: "<date-time from email server>",
    subject: "<subject line text>"
    to: "<who the email was addressed to>",
    to: "<address the email was sent from>"
}

With MsgViewer you can convert .MSG to .EML and then use the utility to obtain the desired JSON.

This functionality looks too specific for me to be a high priority.

However I will look into it when I have time :)

Thanks for the response. That was my plan :) sounds great.

In that vein, I wanted to ask you if you know whether or not I can run MSGViewer as a subprocess in NodeJS --OR-- since I am not a Java guy, what it would take to wrap this in a RESTful API so I can pass .msg and get back .eml files? I know this is not really in scope for you but still thankful for any advice you'd have.

I dont know much about NodeJS, I'm not in position to give you an answer about that point.
MsgViewer as a service looks like a very sexy idea :) I think it's not much work. Just expose a web service using your favorite framework and either embark MsgViewer as a dependency or invoke it through CLI
It may be useful to isolate the GUI part and the service part into different modules. I'll think about it ;)

Hi @curldapps!

It's been a long time and now I plan on exposing a web API to convert formats.
I'm not planning to do a REST API because there is no state to represent.
It would be a simple HTTP API where .msg are handled as bytes stream and .eml & .mbox as characters stream.

Could you progress on this subject so I don't have to reinvent the wheel?
