About this conversion
Converting Parquet to Excel makes analytical data accessible to business users who work in spreadsheets. Parquet files — common outputs from data warehouses, Spark jobs, and model pipelines — become a standard .xlsx file that opens in Excel, Google Sheets, or LibreOffice without any special tooling or programming environment.
Common use cases include exporting a data warehouse query result or model output for distribution to a finance or operations team, sharing analytical results with business stakeholders, and converting Athena or BigQuery query exports for use in Excel-based reports. Parquet's typed schema means the Excel output has correct number and date formatting without manual cleanup.
Excel has a row limit of 1,048,576 rows. If your Parquet file is larger, use the Sample or Head tool to extract a subset first. Complex Parquet types such as nested structs and list arrays are serialised as JSON strings in the Excel cells — if you need flat columns from a complex schema, use the SQL Query tool to flatten before converting.
