How to Convert Each CSV Row into Separate XML Files with Python

Are you looking to streamline your data by converting rows in a CSV file into distinct XML files? If so, you’re not alone. Many developers encounter this challenge when handling large data sets. The problem commonly arises when the transformation process saves all the data into a single XML file instead of creating separate files for each row. In this guide, we will explore a solution to address this issue effectively.

Understanding the Problem

You might have a CSV file containing multiple rows of data. For instance, consider a CSV file with about 200 rows where each row contains two data points. Your goal is to convert each of these rows into its own XML file, resulting in 200 unique XML files.

Initially, you may attempt to read the CSV file and generate XML as follows:

However, the issue arises from writing the output to the same file every time, causing only the last row of data to be saved.

Solution: Generating Separate XML Files

To generate individual XML files for each row in your CSV, you need to ensure that each XML file gets a unique filename. Here’s how to achieve this:

Updated Code Structure

Initialization: Start by reading your CSV file.

Iterate Through Rows: Use a loop to go through each row.

Generate Unique Names: For each XML file, combine the base filename with an index to create a unique name.

Save Each XML File: Write the XML data for each row to its corresponding file.

Sample Code

Here’s the corrected version of the code that does just that:

Explanation of Key Components

File Handling: The code checks if the CSV file exists and if it is of the correct format.

Enumerate: This function helps to get the current count while iterating through the CSV rows, which serves as part of the filename to ensure uniqueness.

XML Creation: minidom is used to create XML documents. Each element is created and appended accordingly.

File Output: The line with open(f"{oFile}_{i}.xml", 'w') opens a new file with a unique name for each row, preventing the overwriting issue.

Conclusion

By following the guidance in this guide, you can effortlessly convert each row of a CSV file into separate XML files. This method not only organizes your data but also allows for better data management practices. Begin using this approach today, and watch your data transformation process become more efficient and effective.
