Parquet to CSV Converter

Data teams hand off query results and warehouse exports as Parquet because it is fast and compact, but the person who actually reads the numbers is often a stakeholder who works in Excel. When a model output or a sales report arrives as a .parquet file, converting to CSV is the difference between the analysis sitting in the file and being reviewed. The flat CSV opens in Google Sheets, Excel, and any text editor, so the handoff works without installing pandas, DuckDB, or extra data tooling on the recipient's machine.

Validating a Parquet file's contents without spinning up a notebook is a common need. Before you trust a dataset in a downstream pipeline, you want to see sample rows, confirm column names match the expected schema, and check for nulls. Converting the file to CSV gives you a fast, inspectable view of the real data, including a preview you can open in a spreadsheet or diff against another export. It is quicker than firing up a Python environment just to eyeball whether the file contains what its name suggests.
