If you're moving spreadsheet data to a data lake, preparing files for big data analysis, or optimizing storage costs, Parquet conversion delivers significant benefits.
Why Convert Excel to Parquet?
- Analytics Platform Support: Upload Excel data to Spark, Athena, BigQuery, or Snowflake in their preferred format.
- Efficient Storage: Parquet's columnar compression significantly reduces file size compared to Excel.
- Query Performance: Enable fast analytical queries that only read required columns from your data.
- Data Lake Ready: Prepare Excel reports for ingestion into S3, GCS, or Azure data lakes.
Supported Excel Formats
- XLSX: Excel 2007 and later (recommended)

Frequently Asked Questions
Which worksheet is converted?
The converter processes the first worksheet in your Excel file. For multi-sheet workbooks, save each sheet as a separate file if needed.
Are Excel formulas preserved?
Formulas are converted to their calculated values. Parquet stores data values, not formulas, which is appropriate for analytics use cases.
