The gap it fixes

JSON-YAML-XML Converter (JetBrains Marketplace id 20297), 10,062 downloads, paid, vendor Syncro Soft -- rated 2.9/5, the lowest of any competitor evaluated for this workspace. Real, verbatim reviewer complaints:

"Not usable with IntelliJ 2024.2.1 (Ultimate Edition)" / "Not usable with IntelliJ 2021.2.2" -- recurring compatibility breaks.
"Works okay, but has problems with UTF-8 characters"
"the tool is not able to convert BIG Files (> 1GB)"
"I was expecting that I can convert editor content without extra dialog that asks me to enter two file paths... it was easier to open a chrome tab with some online converter and copy-paste stuff there"
