Convert Excel spreadsheets to Apache Parquet format for optimized storage and analytics. Transform your XLSX and XLS files into the industry-standard columnar format used by Spark, Athena, BigQuery, and modern data platforms.

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)
XLS: Excel 97-2003 legacy format

The converter reads data from the first worksheet and creates an optimized Parquet schema based on detected column types.

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.
