JavaScript Object Notation (JSON) is an open-standard data format or interchange for semi-structured data. It is text-based and can be read by humans and machines.
Is a JSON file structured?
JSON is an ideal format for larger data that have a hierarchical structured relationship. The structure of a JSON object is as follows: The data are in name/value pairs. … Each data element is enclosed with quotes “” if it is a character, or without quotes if it is a numeric value.
What type of data is JSON?
JSON is a text-based data format following JavaScript object syntax, which was popularized by Douglas Crockford. Even though it closely resembles JavaScript object literal syntax, it can be used independently from JavaScript, and many programming environments feature the ability to read (parse) and generate JSON.
Is the data structured or unstructured?
Structured data is highly specific and is stored in a predefined format, where unstructured data is a conglomeration of many varied types of data that are stored in their native formats.

Structured data vs. unstructured data.
| Structured Data | Unstructured Data | |
|---|---|---|
| Who | Self-service access | Requires data science expertise |
Is JSON a flat file format?
In other cases, you might prefer “flat” JSON, where each input record is represented as a flat sequence of key-value (KV) pairs, without nested structures.
What is a JSON How is it structured?
A JSON object contains zero, one, or more key-value pairs, also called properties. The object is surrounded by curly braces {} . Every key-value pair is separated by a comma. The order of the key-value pair is irrelevant.
What are examples of unstructured data?
Examples of unstructured data are:
- Rich media. Media and entertainment data, surveillance data, geo-spatial data, audio, weather data.
- Document collections. Invoices, records, emails, productivity applications.
- Internet of Things (IoT). Sensor data, ticker data.
- Analytics. Machine learning, artificial intelligence (AI)
Which data type is not part of the JSON standard?
JSON supports a value of type String, Number and Boolean. It does not support octal and hexdecimal values.
What is JSON format example?
JSON vs. XML
| JSON | XML |
|---|---|
| JSON object has a type | XML data is typeless |
| JSON types: string, number, array, Boolean | All XML data should be string |
| Data is readily accessible as JSON objects | XML data needs to be parsed. |
| JSON files are more human-readable. | XML files are less human-readable. |
What are the two main structures compose JSON?
The two primary parts that make up JSON are keys and values. Together they make a key/value pair. Key: A key is always a string enclosed in quotation marks. Value: A value can be a string, number, boolean expression, array, or object.
Does Google use JSON?
Google Prefers JSON-LD Structured Data
Google’s John Mueller made it clear that Google preferred JSON-LD structured data. Personally, I prefer it as well because it’s easier to implement. The scripting language follows a set of easily learned rules and can easily be added or removed from a site.
Can we use SQL for unstructured data?
Structured Query Language (SQL) enables queries on this type of structured data within relational databases. Some relational databases store or point to unstructured data, such as customer relationship management (CRM) applications.
Is Excel structured or unstructured data?
Differences between structured and unstructured data
| Properties | Structured Data | Unstructured Data |
|---|---|---|
| Examples | Excel, Google Sheets, SQL, customer data, phone records, transaction history | Text data, social media comments, phone calls transcriptions, various logs files, images, audio, video |
Why JSON and XML are considered to be semi-structured?
XML and JSON are considered file formats that represent semi-structured data, because both of them represent data in a hierarchical (tree-like) structure. For an example of tree-like structure, consider DOM, which represents the hierarchical structure and while commonly used for HTML.
Can JSON be used to describe structured data that include arrays?
JSON Syntax
JSON defines only two data structures: objects and arrays. An object is a set of name-value pairs, and an array is a list of values.
Which is better XML or JSON?
JSON is faster because it is designed specifically for data interchange. JSON encoding is terse, which requires less bytes for transit. JSON parsers are less complex, which requires less processing time and memory overhead. XML is slower, because it is designed for a lot more than just data interchange.
