Common JSON/YAML Conversion Mistakes

Most conversion problems trace back to a handful of YAML quirks. Knowing them keeps the output correct.

Indentation and types

YAML uses indentation for structure, so a misaligned line changes meaning. It also interprets unquoted values like yes, no and on as booleans — quote them if you mean the strings.

Comments do not survive

Converting YAML to JSON drops comments, because JSON has none. If comments matter, keep the YAML source as the canonical version and treat JSON as a generated artifact.

Frequently asked questions
