- 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.
- An Arrow IPC file holds a data table in Apache Arrow's in-memory columnar layout, so it can be memory-mapped and read without conversion. Feather version 2 files are the same format.
