This post contains some of the best free JSON extractors tools that you can use online to evaluate JSON paths. These tools take a JSON array from you and then let you extract some data from it according to the keys and objects. You can either extract a specific key or you can simply extract an entire node or object. All the websites that I have mentioned here support JavaScript like expressions to extract the data. And you can use these websites to practice JSON data extraction as well.
If you want to be a programmer then you will have to often work with JSON data. Basically, you have to extract some data from it be it an API response or output of some other tools. And JSON extraction needs a little understanding of dictionaries, arrays, etc. And that is what the websites I have mentioned here offer you. The best part is that you don’t need any user account in order to use them. Just give them the JSON you want to short intake output. This is as simple as that.

JSON Path Evaluator by Site24x7 is a nice, simple, and free tool that you can use to validate and extract a matching piece from JSON data against an input expression. It supports a jQuery like syntax and using the expression you can extract a JSON array, a specific value of the array, an entire object, all elements of a specific type, extraction based on condition, and more.

JSON Path Tester by Code Beautify
JSON Path Tester by Code Beautify is another free online JSON evaluator you can use. This is simple and works pretty much like the website above. You just enter a JSON code along with an expression and it will generate the results accordingly. On this website, you can practice your JSON extraction skills. Using this tool, you can extract JSON values from the code, nodes, arrays, values of specific keys, and more. And apart from this there is a JSON beautifier on this website that you can use as well.
There is no sign up required to use this JSON evaluator. Follow the above link to reach the home page of this website and start suing. You simply start by pasting the JSON code that you want to extract some data from. Next, you enter a valid expression and then it will generate the output instantly for you. You can copy that and then enter a different expression to get different results. Even though there is an option on this website to save and share your results, for now it is not working.
Jayway JsonPath Eevaluator
Jayway JsonPath Evaluator is another free open-source JSON validator website that you can use. Just like other tools in this list, it takes JSON and lets you extract data from it using JS like expressions. For now, it is hosted on Heroku but you can also host it on your own using its source code. It offers some extra options while extracting some key values. Just type an expression and choose the normalization options if you want to.
Open this tool from the link above and then enter some JSON code in it. Make sure that it is valid and after that, you can do the extraction. For that, you need to enter an expression in it. The syntax of expression is the same as in the websites above. The jQuery like syntax is easy to remember and you just type the index of the key you want to extract and it will show you the corresponding data. This is as simple as that. However, for now, there is no way to export the extracted data from this website.
Online JsonPath Evaluator Tool
Online JsonPath Evaluator Tool is the last free tool in this list of mine that you can use. Like the other 4 websites here, you just enter some JSON code and JsonPath expressions to see the output. The JsonPath expressions can use the dot-notation and you just have to make sure that you enter the valid expression as well as the input JSON code. It comes with a little guide as well where you can learn about how to construct simple and slightly advanced expressions to extract JSON keys and objects.
Use this website from above and start using it without any sign up or registration. After that, you only need to enter some valid JSON and enter an expression to test. If the entered data is correct, you will see the output in the right pane. A good thing is that this website offers you an option to output paths instead of values. This way, you will have more understanding of the JSON paths.
Final thoughts:
If you are looking for some free online JSON extractor tools then you are at the right place. Just use any website I have mentioned here and evaluate any JSON path to extract meaningful data. All these websites are good and work as intended. Some of them can even beautify the input JSON code. Personally, I will recommend you to use JSONPath Online Evaluator but you are free to try other JSON path evaluator websites.
