CSV Data Handling: A Complete Guide to Processing and Conversion
CSV (Comma-Separated Values) files are a common format for storing and exchanging data. Understanding how to effectively handle and process CSV data is crucial for modern application development. This guide covers everything you need to know about CSV data handling and conversion. For more on data conversion, check out our guide on convert CSV to JSON in Python.
Understanding CSV Format
CSV files are simple text files that store tabular data in a structured format. Each line represents a row, and values within each row are separated by commas (or other delimiters). For more on data formats, see our guide on JSON format example.
