hello @Tex,

I’ve looked at it, but I haven’t found the answer yet.

I mean, I get the content directly and store it in a JavaScript variable.

thank you.

Can you describe a little more of what you’re trying to accomplish?

- You are trying to read in a document (DOCX / ODT / PDF / …) using the API.
- Then you are trying to stick it all into a Javascript variable.
- Then you are ???

Maybe if you describe the goal you are trying to aim for with your program, maybe there’s an alternate way to help or tackle the problem.
