Indesing data merge with plain text qr code

[prestampa29275618e2xc]

Hello everyone,
I have to create a data merge document including a plain text qrcode.
My source is a CSV file from libreoffice.
The trouble comes when I try to insert a line feed or a carriage return.
Using excel formula CHAR(10) or CHAR(13) does not work, because the rendering return just the first line of the text.
Is there a way to fix the issue?
Thanks

Few months ago, on another thread, you've tested reading raw data - with a dedicated app? Or it was someone else?

It was the ZXing code/app  (that's "Zebra Crossing," charmingly enough). There was a web site decoder, which went dark sometime in the past few weeks. There's an outdated Android app, which does not have the raw mode. And the code from around 2014 is on GitHub but not supported.

If there's a second "diagnostic" reader, I haven't found it. One that analyzes everything and reports raw data, error correction mode in use, Version (basically == grid density and code content limit)... would be nice. But no, we have 536 clones with fancy marketing, tracking and malware options.
