Duka alkibla biyu na canjawa — YAML zuwa JSON da JSON zuwa YAML — suna gudana gaba ɗaya a burauzarka ta amfani da wani mai nazari da emitter da aka rubuta da hannu wanda aka gina a shafin, babu ɗakin karatu na YAML na bangare na uku kuma babu uwar garke da abin ya shafa. Hankalin yana zaune a wani module na TypeScript guda ɗaya (lib/yamljson.ts) wanda yake sarrafa mappings, sequences, scalars, harafin ambaton, da cire sharhi na cikin-layi.

   Mai nazarin yana tafiya jerin alamar ta amfani da matakin tazara don tantance tsari. Yana gane abubuwan sequence (- value), maɓallan mapping (key: value), da blocks na cikin gida. Scalars suna wucewa ta wani mataki na coercion da aka bayar da nau'i wanda yake sarrafa null, boolean, cikakkun lamba (yana ƙin ƙimomin sifili-jagora kamar 007 don guje wa gurɓata bayanai shiru), da floats — tare da wani yanayi na zaɓi wanda yake kiyaye kalmomi-bare na YAML 1.1 kamar yes, no, on, da off a matsayin harafi maimakon canja su zuwa boolean.
