Why convert Excel to Parquet?
Convert Excel to Parquet to break Excel's 1M row limit, get 10-100x faster queries (especially column operations), reduce file size by 80-90%, and work with billions of rows. Perfect when Excel is too slow or can't open your data.
How is Parquet better than Excel for large data?
Parquet has no row limits (vs Excel's 1M), queries are 10-100x faster for column operations, files are 80-90% smaller, and it handles billions of rows efficiently. Excel is great for business reports, but Parquet is designed for big data analytics.
Will formulas be preserved?
Parquet stores values, not formulas. When you convert Excel to Parquet, formulas are calculated and their results are saved. This is perfect for data analysis where you need values, not the calculation logic.
What happens to multiple sheets?
Each Excel sheet is converted to a separate Parquet file. For example, if you have 'Report.xlsx' with 3 sheets, you'll get 'Sheet1.parquet', 'Sheet2.parquet', and 'Sheet3.parquet'.
Can I convert back to Excel?
Yes! FileHop supports bidirectional conversion. Convert Parquet back to Excel anytime for business reporting or sharing with Excel users. Note: Excel has a 1M row limit, so large Parquet files will be truncated or split.
How much faster will my analysis be?
Typically 10-100x faster for filtering, searching, and aggregations, especially on column-specific operations. For example, filtering 50M rows by a column: Excel can't open it (over 1M limit), Parquet filters in 2 seconds.
What tools can read Parquet files?
Parquet is supported by: FileHop (GUI), Python pandas, Apache Spark, DuckDB, BigQuery, Snowflake, AWS Athena, Databricks, and most modern data tools. It's an industry standard.
Is Excel to Parquet conversion free?
Completely free with unlimited conversions. No file size limits, no watermarks, no credit card required.
