What does it mean

XML file is a text file designed for structured data transfer between systems. It is not a format primarily intended for "human reading," but rather for exchanging information between applications, websites, or databases.

XML File: What is it and why is it important for data transfer?

The main role of an XML file is to transfer data in a clearly defined structure. Each piece of information has its place, which minimizes errors during processing.

XML file is mainly used because:

• it is readable for both humans and machines,
  
• it has a clear logical structure,
  
• it is compatible with various systems and platforms.
  
  

Thanks to this, XML has become the standard for data exchange on the web and in enterprise systems.

XML Format: What are the main advantages of this data standard?

XML format is flexible and extensible. This means it can be tailored to the specific needs of a project without losing its readability or functionality.

The main advantages of XML include:

• unambiguous data structure,
  
• simple validation and control,
  
• long-term compatibility.
  
  

This is why XML is used where data stability and accuracy are needed – for example, in integrations or automated processes.

Use in E-commerce: XML Feeds for Price Comparators and PPC Campaigns

In the e-commerce environment, XML plays a key role. It is most often used in the form of XML feeds, which contain information about products, prices, or availability.

These feeds are used, for example, for:

• price comparators,
  
• product campaigns in Google Ads,
  
• marketplace platforms.
  
  

Thanks to XML feeds, an e-shop can be connected to external tools without manual data management.

Working with Data: How to Properly Open and Edit XML?

Opening an XML file can be done in several ways. Since it is a text format, it can be opened in a regular text editor or directly in a web browser.

When editing XML files, it is important to:

• maintain the correct tag structure,
  
• adhere to data hierarchy,
  
• verify that the file is still valid after editing.
  
  

An incorrectly edited XML file can cause errors during data import or processing, so accuracy is key.
