Parse text as JSON or XML (Power Query)? ›

XML is complex and less flexible. JSON supports numbers, objects, strings, and Boolean arrays. XML supports all JSON data types and additional types like Boolean, dates, images, and namespaces. JSON has smaller file sizes and faster data transmission.

You perform explicit XML parsing when you invoke the XMLPARSE function on the input XML data. You can use the result of XMLPARSE in any context that accepts an XML data type. For example, you can use assign the result to an XML column or use it as a stored procedure parameter of type XML.

Example - Parsing JSON

Use the JavaScript function JSON.parse() to convert text into a JavaScript object: const obj = JSON.parse('{"name":"John", "age":30, "city":"New York"}'); Make sure the text is in JSON format, or else you will get a syntax error.

Parse JSON text

Select Transform > Parse > JSON. Select Record to see the values.

It did not require the rather inconvenient “data binding” and “data serialization” steps that were notoriously difficult when using XML-based APIs. Instead, JSON allowed APIs to represent structured data in a way that simply was a better fit for the conceptual universe that most developers live in.

Q: Is XML still being used? A: XML is still used in many circ*mstances where its advantages come to the forefront. This is particularly true in applications or environments where document markup and metadata are important or where you need to work with XHTML or SVG.

DOMParser Method

The DOMParser object has a method called parseFromString that parses a string that contains either HTML or XML and produces a document object (HTMLDocument or XMLDocument). This allows you to directly load and manipulate XML data within your JavaScript code.

How to parse JSON to XML? ›

To parse XML in Python, we can use different packages. However, the most popular one is ElementTree. ElementTree allows for searching through XML files using their elements. It also supports most of the XPath syntax, such as matching by positions, attributes and text.

JSON uses a map data structure, with key-value pairs, making it simpler and more intuitive. XML, on the other hand, uses a tree structure, which can be more complex but also more flexible. JSON is generally faster and easier to use, making it the preferred choice for web APIs and mobile applications.

String data can be easily converted to JSON using the stringify() function, and also it can be done using eval(), which accepts the JavaScript expression that you will learn about in this guide.

Select Home > Split Column > By Delimiter. The Split a column by delimiter dialog box appears. In the Select or enter a delimiter drop-down, select Colon, Comma, Equals Sign, Semicolon, Space, Tab, or Custom. You can also select Custom to specify any character delimiter.
