Welcome to the forum @sinmeera

A link to where we can read what an HL7 message is would be helpful, to save us googling.

It is health related and somewhat complex 😀

I dont know HL7 but there are a few packages on Github and NPM.

for example, you could, in a function node, add [this module](https://www.npmjs.com/package/hl7-standard) on the setup tab then in the "on message" write some standard JS to create your HL7 message.

I assume you're using one of the pipe delimited formats and not FHIR? You may have some luck playing with the CSV node using | as your delimiter. Can you give an example of your input data (with PII stripped of course?) I did basically the opposite of this (parsing HL7 into JS objects to push in real time to influx) a couple years back and found that it wasn't terribly tough.
