Yes you can, simply as a string. Here's your parsingMatrix from your other comment: { "if":[ { "or":[ { "===":[ { "var":"credentialData.rapidSarsCov2PCRTest.testResult" }, "negative" ] }, { "===":[ { "var":"credentialData.covid19Vaccination.hasVaccination" }, true ] } ] }, "valid", "invalid" ] } Here it is rewritten in a way more similar to how a human writes Lisp: { "if": [{"or": [{"===":[{ "var":"credentialData.rapidSarsCov2PCRTest.testResult" }, "negative" ]}, {"===":[{ "var":"credentialData.covid19Vaccination.hasVaccination" }, true ]}]}, "valid", "invalid"]}; Here it is as an s-expression, which you can store in a string: (if (or (= (var "credentialData.rapidSarsCov2PCRTest.testResult") "negative") (= (var "credentialData.covid19Vaccination.hasVaccination") #t)) "valid" "invalid") But, if you really have an intense hatred for adding an additional parsing step on top of the JSON, you can still improve over JsonLogic with just JSON primitives used in a cleaner way that more directly represents that s-expression. ["if", ["or", ["=", ["var", "credentialData.rapidSarsCov2PCRTest.testResult"], "negative"], ["=", ["var", "credentialData.covid19Vaccination.hasVaccination"], true]], "valid", "invalid"] It's still uglier than s-expressions where you can tell symbols and strings apart with more ease, but without all the syntactical noise of JSON objects combined with arrays.
