- Description
- An XLSX file is an Excel spreadsheet created by Microsoft Excel or another spreadsheet program, such as OpenOffice Calc or Apple Numbers. It stores data in worksheets, which contain cells arranged in a grid of rows and columns, and may also contain charts, mathematical functions, styles, and formatting. XLSX files are commonly used to store financial data and to create simple or complex mathematical models.
- A Parquet file is a columnar data table: each column is stored on its own, compressed and typed, so analytics tools can read only the columns they need. It is the common exchange format of data lakes, Spark, pandas and DuckDB.
