Fix CSV DictWriter Field Order

Python's csv.DictWriter is convenient for writing CSV files from dictionaries. However, it can sometimes reorder your columns based on the keys it encounters, which might not be the order you intended.

This can lead to inconsistent file structures, especially when dealing with data that needs to be processed by other systems expecting a specific column sequence.

The CSV DictWriter Field Order Fixer is a small helper script designed to address this. It ensures that the columns in your output CSV file are written in the precise order you define. You provide the desired field names in the correct sequence, and the tool writes each row accordingly, overriding the default behavior of DictWriter that might lead to reordering.

If you've ever struggled with DictWriter changing your column order or if you need strict control over your CSV file structure, this tool is for you. It’s a straightforward solution for maintaining data integrity and predictability in your CSV exports.
