Converting Text Tables to CSV Files: A Simple Guide Using Python

In today's data-driven world, it's common to encounter data in various formats. One such format is a text file containing tabulated data. If you've ever found yourself needing to convert a formatted text table into a more manageable CSV file, you may be wondering how to achieve it. In this post, we'll walk you through a simple solution using Python to parse text in a table format and save the results in CSV format.

The Challenge: Parsing a Text Table

Imagine you have a text file structured as follows:

While it seems straightforward, the process may be a bit tricky, especially if you're not familiar with Python programming. But fear not, with the right approach, you can easily accomplish this task!

Solution: Using Python to Parse and Convert

Moving from a text table to a CSV file requires cleaning up the data and structuring it correctly. We'll use Python, along with the Pandas library, to simplify this task. Below is a step-by-step breakdown of how to accomplish this.

Step 1: Setting Up Your Python Environment

Before we begin, ensure you have Pandas installed in your Python environment. You can install it via pip if you haven't already:

Step 2: Writing the Parsing Script

Here’s the step-by-step code that you can use to parse the table and convert it into a DataFrame:

Step 3: Understanding the Code

Here's a breakdown of the code:

Import Libraries: We use re for regular expressions and pandas to create a DataFrame.

Define Input: The variable txt holds the structured table as a string.

Regular Expressions: is_row identifies rows, while is_dashed_line helps skip lines with dashes (not part of actual data).

Data Processing: We loop through each line, clean it, and parse the data into a list called data. The last row's data can be concatenated if it spans multiple lines.

DataFrame Creation: Finally, we create a Pandas DataFrame and print it out.

Step 4: Executing the Script

Once you have your script ready, run it, and you should see the DataFrame printed in your console, formatted just as you wanted! After that, you can easily export this DataFrame to a CSV file:

Conclusion

Parsing tables from a text format into a structured CSV file doesn’t have to be complicated. By leveraging Python and Pandas, you can efficiently process and convert your data with a few lines of code. Next time you receive raw data in a text table format, remember this guide and simplify your data workflows!
