One final question, is it possible to specify in the request.json the name of a template and data file in the directory that the executable is run in. For example I have a report.json data file that should bind to test.html file and I would to put that information in a single request.

Ahh, thank you, one correction though is that it's

jsreport.exe render --request request.json --out file.pdf

On this page: https://jsreport.net/learn/windows-single-executable

It says that the following command should work:

jsreport.exe --render request.json --output file.pdf

but I get

"Unknown arguments: render, output" when I run it.
