How to create ourself json to json schema in python and validate with json response? Do we have any code?

[@RaghavPal]

Hi Kiruba, Yes, you can create a JSON schema and validate JSON responses in Python using the jsonschema library. Can check here - pynative.com/python-json-validation/

[@kirubababu9255]

@@RaghavPal Thanks for your soln!! Is there any way to convert json response to json schema?

[@RaghavPal]

To convert a JSON response to a JSON Schema in Python, you can use the jsonschema library. Here is an example of how to do it: import jsonschema # Your JSON response response = { "name": "John Doe", "age": 30, "email": "[e-mail]" } # Generate the JSON Schema schema = jsonschema.Draft7Validator.check_schema(response) # Print the schema print(schema)

Hii sir , I have one JSON DATA file with datas in it. Now I want to EDIT or modify the DATAS OF VALUES from that json file , but I can't able to do that for JSON ARRAY, please give me some example to refer for that

[@RaghavPal]

## Modifying data in a JSON file with an array There are various ways to modify data in a JSON file with an array, depending on your specific needs and programming language. Here are some examples: **1. Python:** ```python import json with open("data.json", "r") as f: data = json.load(f) # Accessing specific element in array data["array_name"][0]["key"] = "new_value" # Looping and modifying elements for item in data["array_name"]: if item["condition"]: item["key"] = "modified_value" # Updating the JSON file with open("data.json", "w") as f: json.dump(data, f, indent=4) ``` **2. JavaScript:** ```javascript const fs = require('fs'); const data = JSON.parse(fs.readFileSync('data.json', 'utf8')); // Accessing specific element in array data.arrayName[0].key = 'newValue'; // Looping and modifying elements data.arrayName.forEach(item => { if (item.condition) { item.key = 'modifiedValue'; } }); // Updating the JSON file fs.writeFileSync('data.json', JSON.stringify(data, null, 2)); ``` **3. Shell Script:** ```sh jq '.array_name[0].key = "new_value"' data.json > data_new.json ``` **4. JSON Online Tools:** Several online tools allow you to edit JSON data directly in your browser. You can search for "JSON editor" or "JSON online tool" to find one that suits your needs. **Additional Tips:** * Make sure you have the correct file path and access permissions. * Always back up your original JSON file before making any changes. * Use descriptive variable names and comments to improve code readability. * Consider using libraries or modules specifically designed for JSON manipulation for more complex tasks. These examples provide a basic framework for modifying data in a JSON file with an array. Remember to adapt the code to your specific data structure and desired modifications.

[@Rajivrocks-Ltd.]

Can you use a JSON Schema to filter out unwanted data? So you have a huge JSON file you get from an endpoint but you just want 2 or 3 fields from it?

[@RaghavPal]

That is better done using JSON Path

@@RaghavPal ah okay thank you ill look into that!

Hi sir how to convert one json schema to another different json schema in python code

[@RaghavPal]

Hemanth To convert one JSON schema to another different JSON schema in Python code, you can use the following steps: 1. **Import the necessary libraries.** ```python import json import jsonschema ``` 2. **Load the source JSON schema.** ```python with open("source_schema.json", "r") as f: source_schema = json.load(f) ``` 3. **Validate the source JSON schema.** ```python jsonschema.validate(source_schema, jsonschema.Schema()) ``` 4. **Convert the source JSON schema to the new JSON schema.** ```python new_schema = jsonschema.Draft7Validator(source_schema).schema ``` 5. **Save the new JSON schema.** ```python with open("new_schema.json", "w") as f: json.dump(new_schema, f, indent=4) ``` Here is an example of a Python code that converts a JSON schema from Draft 4 to Draft 7: ```python import json import jsonschema # Load the source JSON schema. with open("source_schema.json", "r") as f: source_schema = json.load(f) # Validate the source JSON schema. jsonschema.validate(source_schema, jsonschema.Schema()) # Convert the source JSON schema to the new JSON schema. new_schema = jsonschema.Draft7Validator(source_schema).schema # Save the new JSON schema. with open("new_schema.json", "w") as f: json.dump(new_schema, f, indent=4) ``` You can use the same approach to convert JSON schemas from any draft to another draft.

Like you can create XML API samples from XML Schema can we create JSON API requests from JSON Schema?

[@RaghavPal]

Hi Movi, we can use JSON schema to annotate and validate json documents

[@movimovimania5521]

@@RaghavPal Thanks what i meant is rolling out JSON API requests using JSON Schema, not just for validation / annotation

[@RaghavPal]

Not exactly, its for checking the format, structure. Basically it checks if your Json message conforms with the schema

[@movimovimania5521]

@@RaghavPal right, so basically it's not similar to XML Schema where an XML schema is capable of populating an XML API request but JSON schema simply validates, but isn't capable of populating a sample JSON request ... that feels a bit odd considering JSON is so popular.

[@RaghavPal]

See you can generate a sample document, but will need to add the values and data www.liquid-technologies.com/online-schema-to-json-converter stackoverflow.com/questions/21894873/generate-sample-json-output-from-json-schema

[@emrentoelluminiados]

how can i find type and properties list?

[@RaghavPal]

Emre Based on what i infer from your query.. In JSON Schema, you can define the type of a schema and specify its properties. Let's break it down: 1. Data Types: - JSON Schema defines several basic data types: - String: Represents text values. - Number: Includes both integers and floating-point numbers. - Object: Represents structured data with key-value pairs. - Array: Contains an ordered list of values. - Boolean: Represents true or false. - Null: Represents the absence of a value. 2. Example Schema: Here's a simple example of a JSON Schema that defines an object with a single property: ```json { "$schema": "json-schema.org/draft-04/schema", "title": "Product", "description": "A product from Acme's catalog", "type": "object", "properties": { "id": { "description": "The unique identifier for a product", "type": "integer" } }, "required": ["id"] } ``` In this schema: - The type is set to "object." - The "id" property is of type "integer." 3. Property Constraints: - You can add constraints to properties using keywords like `minimum`, `maximum`, `pattern`, and more. - For example, you can specify a numeric range for a property or require certain properties to be present. Remember to adapt these concepts to your specific use case --
