+# jsontools
+
+Handy command line tools for dealing with json data.
+
+## Tools
+
+- **pp_json** - pretty prints json
+- **is_json** - returns true if valid json; false otherwise
+- **urlencode_json** - returns a url encoded string for the given json 
+- **urldecode_json** - returns decoded json for the given url encoded string
+
+## Usage
+Usage is simple...just take your json data and pipe it into the appropriate jsontool.
+```sh
+<json data> | <jsontools tool>
+```
+## Examples
+
+##### pp_json
+
+```sh
+# curl json data and pretty print the results
+curl https://coderwall.com/bobwilliams.json | pp_json
+```
+
+##### is_json
+```sh
+# pretty print the contents of an existing json file
+less data.json | is_json
+```
+
+##### urlencode_json
+```sh
+# json data directly from the command line
+echo '{"b":2, "a":1}' | urlencode_json
+```
+
+##### urldecode_json
+```sh
+# url encoded string to decode
+echo '%7B%22b%22:2,%20%22a%22:1%7D%0A' | urldecode_json
+```
