How to use the Python openpyxl library to read Excel data: install the openpyxl import library, open the workbook, select the worksheet, read the cell value, read the value of a specific area, read the formula result
How to use Python to read Excel data
Python provides a variety of built-in modules and third-party libraries to read Excel data. Here's how to read Excel data using one of the most common methods, the openpyxl library:
Step 1: Install openpyxl
<code>pip install openpyxl</code>
Step 2: Import the library
import openpyxl
Step 3: Open the workbook
workbook = openpyxl.load_workbook('example.xlsx')
Step 4: Select the worksheet
worksheet = workbook.active
Step 5: Read the cell value
value = worksheet.cell(row=1, column=1).value
This method will return the value of cell A1. To read the cell value of the entire worksheet, you can use the following loop:
for row in worksheet.rows: for cell in row: value = cell.value
Step 6: Read the value of a specific range
values = worksheet.range('A1:C5').value
This method will return A1 to the value of the cell in the range C5.
Step 7: Read the formula result
value = worksheet.cell(row=1, column=1).value
This method will return the result of the formula in cell A1, not the formula itself.
Example:
import openpyxl # 打开工作簿 workbook = openpyxl.load_workbook('example.xlsx') # 选择工作表 worksheet = workbook.active # 读取特定区域的值 values = worksheet.range('A1:C5').value # 逐行和逐列打印值 for row in values: for cell in row: print(cell)

Python is an interpreted language, but it also includes the compilation process. 1) Python code is first compiled into bytecode. 2) Bytecode is interpreted and executed by Python virtual machine. 3) This hybrid mechanism makes Python both flexible and efficient, but not as fast as a fully compiled language.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
