Escaping basics
The escape sequences you use most often in JSON strings.
json
{
"html": "<\/script>"

Encoding pitfalls
Common mistakes when JSON crosses system boundaries.
text
Content-Type: application/json; charset=utf-8Notes
Most modern APIs and parsers assume UTF-8.
JSON string containing JSON
Sometimes one field stores another JSON document as a string.

json
{
"payload": "{\"event\":\"signup\",\"ok\":true}"
}Notes
This is valid, but consumers must decode the outer JSON and then parse the inner string separately.
bash
jq '.payload | fromjson' event.jsonNotes
Useful when a system stores JSON inside a string field.
Encode structured data as a JSON string
Turn a value into a JSON-encoded string.

bash
jq -n '{event:"signup",ok:true} | @json'Notes
Helpful when generating escaped JSON for embedding in another payload.
