Among the standard data format types, there is a special type of data type, which is hierarchical data. Hierarchical data is completely different from standard structured data. The most frequently used data types in practical applications are as follows.
- XML data format
- Json data format
- Yaml data format
We will share with you the integration of XML format data in this section, and the integration of Json data format in the next section. The Yaml format is currently not directly supported by PowerQuery, but there are other ways to extract data, and we will not discuss this issue in this book. Under the hierarchical data structure, the data is displayed in the following hierarchical manner, and the figure shows the format of the hierarchical data.
The data format of XML is to realize the description of data in the form of tag pairs, starting with <tag> and ending with </tag>. We will use the following case as a case for importing XML data into Excel.
