Reading Excel Files

The read_excel() method can read Excel 2003 (.xls) and Excel 2007 (.xlsx) files using the xlrd Python module.

Writing Excel Files

Files with a .xls extension will be written using xlwt and

those with a .xlsx extension will be written using xlsxwriter (if available) or openpyxl.

It was born from lack of existing library to read/write natively from Python the Office Open XML format.

Development of this module would not have been possible without the document "OpenOffice.org's Documentation of the Microsoft Excel File Format" ("OOo docs" for short). The latest version is available from OpenOffice.org in PDF format and ODT format. Small portions of the OOo docs are reproduced in this document. A study of the OOo docs is recommended for those who wish a deeper understanding of the Excel file layout than the xlrd docs can provide.
