python 3 操作 excel

Library for developers to extract data from Microsoft Excel (tm) spreadsheet files

Extract data from Excel spreadsheets (.xls and .xlsx, versions 2.0 onwards) on any platform. Pure Python (2.6, 2.7, 3.2+). Strong support for Excel dates. Unicode-aware.

Library to create spreadsheet files compatible with MS Excel 97/2000/XP/2003 XLS files, on any platform, with Python 2.6, 2.6, 3.3+
This is a library for developers to use to generate spreadsheet files compatible with Microsoft Excel versions 95 to 2003.

This package provides a collection of utilities for working with Excel files. Since these utilities may require either or both of the xlrd and xlwt packages, they are collected together here, separate from either package.

Currently available are:

xlutils.copy
Tools for copying xlrd.Book objects to xlwt.Workbook objects.
xlutils.display
Utility functions for displaying information about xlrd-related objects in a user-friendly and safe fashion.
xlutils.filter
A mini framework for splitting and filtering Excel files into new Excel files.
xlutils.margins
Tools for finding how much of an Excel file contains useful data.
xlutils.save
Tools for serializing xlrd.Book objects back to Excel files.
xlutils.styles
Tools for working with formatting information expressed in styles.
