使用python的xlrd模块读取excel内容

基础操作

测试Excel的内容如下

 

 代码

import xlrd as x

local_filepath = r"D:\Python\Students.xlsx"

# Open work book, no need to close it
wb = x.open_workbook(local_filepath)

# Open work sheet
ws = wb.sheet_by_index(0)

# sheet_by_name
# ws = wb.sheet_by_name('Sheet1')

# Get row count and column count
print("Work sheet row count: {0}, column count: {1}".format(ws.nrows, ws.ncols))

# Get cell value
print("Get Cell(0, 0) value:", ws.cell_value(0, 0))

# Get row values
for i in range(ws.nrows):
    print(ws.row_values(i))

# Get rows with generator
ws.get_rows()

# Get column values
for i in range(ws.ncols):
    print(ws.col_values(i))

###############################################################
# Cell is empty
emptycell = ws.cell_value(2, 1)
emptycell == ''
# Output True

# Cell is date
from datetime import datetime
from xlrd import xldate_as_tuple
date = datetime(*xldate_as_tuple(ws.cell_value(2, 3), 0))
datecell = date.strftime('%m/%d/%y %H:%M')
print(datecell)

输出

 

注意知识点:

1. 打开是不需要显示关闭的.

2. Excel的单元格内容可以为空,读出来的值就是空字符 ''

3. Excel是允许使用函数产生特定值的,比如当前日期.

4. xlrd读的单元格内容是有类型的. 具体参考ctype. 类型值是类似1,2,3,4.比如日期就是3.

5. 对于日期格式是需要做特殊处理格式转换,不做处理就是一串浮点数.
