Building a Zero-Dependency CSV-to-JSON Converter

Short summary

A concise tutorial showing how to convert CSV files to JSON using only Python's standard library (csv and json modules), avoiding third-party dependencies like pandas. The approach uses csv.DictReader for automatic header parsing and json.dump for human-readable output, returning a row count for quick sanity checks. The author notes limitations with irregular real-world CSV files but positions this as sufficient for most quick spreadsheet-to-API pipelines.
