Transform XML Files to CSV in PowerShell: A Step-by-Step Guide

If you're dealing with multiple XML files stored in various subfolders and you want to convert them into CSV format using PowerShell, you're in the right place! Many developers and system admins face the challenge of processing files in bulk. In this guide, we will tackle this problem step by step, ensuring you can efficiently convert XML files to CSVs, saving them with the original filenames in a different directory.

The Problem Statement

You might be in a situation where you have XML files spread across multiple folders. Your goal is to:

Read these XML files.

Convert their contents into CSV format.

Save the resulting CSV files in a specific folder while retaining the original filenames (with a .csv extension).

For example:

\path\to\files\alpha\testing123.xml should be saved as \path\to\output\files\testing123.csv

\path\to\files\bravo\production789.xml should be saved as \path\to\output\files\production789.csv

Solution Overview

To solve this problem, we will make use of the Get-ChildItem cmdlet to fetch all XML files recursively and iterate through them to convert their content. By using appropriate PowerShell functions, we will save the newly created CSV files in the destination directory.

Step-by-Step Solution

Let’s break down the solution into digestible parts:

1. Retrieve XML Files

First, we need to gather all XML files in a specified path recursively. We can do this using the command:

2. Loop Through Each XML File

Now that we have all the XML files, we can loop through each one and read its content. The basic structure looks like this:

3. Convert XML Content to CSV

Here is where your logic for converting XML to CSV will be implemented. This depends on your specific use case, so be sure to add the necessary conversion code where indicated.

4. Construct New Filename for CSV

The next step is to create a new filename for the CSV file based on the XML file's name. This can be done using the -replace operator:

5. Define Output Path

Then, you need to create the complete output path by joining the new filename with your desired output directory:

6. Write the CSV Content to File

Finally, output the CSV content using Set-Content:

Conclusion

By following the steps outlined in this guide, you can efficiently convert multiple XML files to CSV format, ensuring that your output files are neatly organized with the original filenames. This will save you a significant amount of time and effort, especially when handling large numbers of files.

PowerShell is an incredibly powerful tool for automating such tasks, and with practice, you'll find it easy to tackle more complex file manipulations. Happy scripting!
