Replace a boolean field in JSON with sed

I am trying to replace a boolean inside a JSON string using sed.

STRING: "should-replace":false

How would I use sed to replace the false with true?

In awk:

$ awk -F: '/should-replace/{$2=($2=="false"?"true":"false")}1' file
"should-replace" true

Notice: false -> true, everything else (meant to mean true) -> false.

Try this - 

sed '/should-replace/s/false/true/' f

Very straightforward:

sed "s/\"should-replace\":false/\"should-replace\":true/g"
