# Another Parsing JSON Question!

#1

I’m attempting to parse some JSON that I have in a string variable. I’ve tried valid JSON.

For example the data returned by:

`http://api.wunderground.com/api/Your_Key/conditions/q/CA/San_Francisco.json`

Except instead of calling the URL I am just pasting the value in. I’m not actually trying to call this API, I want to pass the JSON to a piston as a variable which is why I’m testing this out. Anyways, it fails every time. Much simpler JSON also fails.

You will need to use a backslash `\` to escape all `{}\` characters in the JSON. Since all strings in webCoRE support `{ variableName }` interpolated values it ends up trying to handle your JSON as if it were a webCoRE expression.

For example, `{ "response": { "version": "0.1" } }` will need to be written as `\{ "response": \{ "version": "0.1" \} \}`. Then you should be able to use the Parse JSON string action and interact with the data via the `\$json` system variable (e.g. `\$json.response.version`).

Well shit, that isn’t going to work. It would be a pain to type all of the escape characters. Oh well, I was just avoiding becoming a regular expressions expert. Now will have to do that.

A little late to the party but:

Set variable {myJson} = replace(replace(replace({\$response}, “”, “\”),"{", “{”), “}”, “}”)
