CSV Formatter for Config Files

About This Tool

Configuration files are at the heart of modern software development — from package.json and tsconfig.json to VS Code settings and cloud infrastructure templates. This CSV Formatter for Config Files is tailored for processing CSV configuration files with the precision and care they require. Configuration files often contain comments (in formats that support them), version-specific settings, and carefully structured hierarchies that must be preserved during formatting. The tool processes these files while maintaining all data integrity, ensuring that indentation reveals the logical structure of configuration sections, nested settings, and conditional values. Whether you are cleaning up auto-generated configuration, merging settings from multiple sources, or preparing config files for documentation, this tool handles the task reliably.

What is CSV Formatter?

A CSV formatter takes raw comma-separated data and transforms it into a visually aligned table where columns are padded with spaces to create consistent widths. Raw CSV data is difficult to read because columns do not align, especially when values have different lengths. The formatter calculates the maximum width for each column across all rows, then pads every value to create uniform column alignment. This makes CSV data immediately readable in text editors, terminals, and documentation without needing a spreadsheet application. The tool also reports the total number of rows and columns, giving you a quick overview of the dataset structure.
