Python3 integrated xlrd

1. Follow the xlrd module

pip install xlrd

2. Use of xlrd function

2.1: Import xlrd module

import xlrd

2.2: Open the specified file

x1 = xlrd.open_workbook("data.xls")

2.3: Get the sheet:

• Get all sheet names: x1.sheet_names()
• Get the number of sheets: x1.nsheets
• Get all sheet objects: x1.sheets()
• Search by sheet name: x1.sheet_by_name("test")
• Search by index: x1.sheet_by_index(3)

# -*- coding:utf-8 -*-

import xlrd
import os

filename = "demo.xls"
filePath = os.path.join(os.getcwd(), filename)

print filePath

# 1、打开文件
x1 = xlrd.open_workbook(filePath)

# 2、获取sheet对象
print 'sheet_names:', x1.sheet_names()  # 获取所有sheet名字
print 'sheet_number:', x1.nsheets        # 获取sheet数量
print 'sheet_object:', x1.sheets()       # 获取所有sheet对象
print 'By_name:', x1.sheet_by_name("test")  # 通过sheet名查找
print 'By_index:', x1.sheet_by_index(3)  # 通过索引查找

2.4 Get the summary data of the sheet:

• Get the sheet name: sheet1.name
• Get the total number of rows: sheet1.nrows
• Get the total number of columns: sheet1.ncols

# -*- coding:utf-8 -*-

import xlrd
import os
from datetime import date,datetime

filename = "demo.xls"
filePath = os.path.join(os.getcwd(), filename)
print filePath

# 打开文件
x1 = xlrd.open_workbook(filePath)

# 获取sheet的汇总数据
sheet1 = x1.sheet_by_name("plan")
print "sheet name:", sheet1.name   # get sheet name
print "row num:", sheet1.nrows  # get sheet all rows number
print "col num:", sheet1.ncols  # get sheet all columns number

2.5 Cell reading

2.5.1 Row operations

• sheet1.row_values(0) # Get all the contents of the first row, merge the cells, display the value in the first row, and leave the others blank.
• sheet1.row(0) # Get the cell value type and content
• sheet1.row_types(0) # Get cell data type

# -*- coding:utf-8 -*-

import xlrd
import os
from datetime import date,datetime

filename = "demo.xls"
filePath = os.path.join(os.getcwd(), filename)

x1 = xlrd.open_workbook(filePath)
sheet1 = x1.sheet_by_name("plan")

# 单元格批量读取
print sheet1.row_values(0)  # 获取第一行所有内容，合并单元格，首行显示值，其它为空。
print sheet1.row(0)         # 获取单元格值类型和内容
print sheet1.row_types(0)   # 获取单元格数据类型

2.5.2 Column operation

• sheet1.row_values(0, 6, 10) # Take the first row, the 6th to 10th columns (excluding the 10th table)
• sheet1.col_values(0, 0, 5) # Take the first column, rows 0~5 (excluding row 5)
• sheet1.row_slice(2, 0, 2) # Get the cell value type and content
• sheet1.row_types(1, 0, 2) # Get cell data type

# -*- coding:utf-8 -*-

import xlrd
import os
from datetime import date,datetime

filename = "demo.xls"
filePath = os.path.join(os.getcwd(), filename)

print filePath

# 1、打开文件
x1 = xlrd.open_workbook(filePath)
sheet1 = x1.sheet_by_name("plan")

# 列操作
print sheet1.row_values(0, 6, 10)   # 取第1行，第6~10列（不含第10表）
print sheet1.col_values(0, 0, 5)    # 取第1列，第0~5行（不含第5行）
print sheet1.row_slice(2, 0, 2)     # 获取单元格值类型和内容，同sheet1.row(0)
print sheet1.row_types(1, 0, 2)     # 获取单元格数据类型

2.6 Reading a specific cell

2.6.1 Get cell value:

• sheet1.cell_value(1, 2)
• sheet1.cell(1, 2).value
• sheet1.row(1)[2].value 

2.6.2 Get the cell type:

• sheet1.cell(1, 2).ctype
• sheet1.cell_type(1, 2)
• sheet1.row(1)[2].ctype

# -*- coding:utf-8 -*-

import xlrd
import os
from datetime import date,datetime

filename = "demo.xls"
filePath = os.path.join(os.getcwd(), filename)

x1 = xlrd.open_workbook(filePath)
sheet1 = x1.sheet_by_name("plan")

# 特定单元格读取
# 取值
print sheet1.cell_value(1, 2)
print sheet1.cell(1, 2).value
print sheet1.row(1)[2].value

#取类型
print sheet1.cell(1, 2).ctype
print sheet1.cell_type(1, 2)
print sheet1.row(1)[2].ctype

2.7 xlrd supports data types

• Empty: 0
• String: 1
• Number: 2
• Date: 3
• Boolean: 4
• error：5
