使用openpyxl.load_workbook报错找不到文件，切换正确目录仍无法获取Excel类

I totally get that frustrated feeling when you swear you're in the right directory but the file still can't be found—let's break down possible fixes step by step:

• Double-check your working directory and file details
  Even if you think you switched to the correct folder, it's worth verifying programmatically. Add this line to your code to print your current working directory:

  import os
  print(os.getcwd())
  

  Compare this output to the actual folder where wellbeing.xlsx lives. Also, watch out for:

  • Case sensitivity: On Linux/macOS, Wellbeing.xlsx is not the same as wellbeing.xlsx, but Windows ignores case—make sure your code matches the exact filename.
  • Hidden trailing spaces: Sometimes filenames accidentally get a space at the end (like wellbeing.xlsx ), which is easy to miss visually.

• Use an absolute path instead of a relative one
  Relative paths can be finicky if your script's working directory isn't what you expect. Grab the full absolute path to your file (right-click the file and select "Copy path" on most systems) and use that directly in your code. For example:

  # Windows example
  path = "C:/Users/YourUsername/Documents/wellbeing.xlsx"
  # Linux/macOS example
  path = "/home/YourUsername/Documents/wellbeing.xlsx"
  

  Then pass this path variable to your Excel reading function.

• Make sure the file isn't locked
  If you have wellbeing.xlsx open in Excel or another program, it might be locked and prevent Python from accessing it. Close all instances of the file and try running your code again.

• Verify your Excel-reading code logic
  Assuming you're using a library like pandas or openpyxl, here's a quick example of a robust setup that checks the path first:

  import pandas as pd
  import os
  
  filename = "wellbeing.xlsx"
  # Check if file exists in current directory
  if not os.path.isfile(filename):
      print(f"Error: {filename} does not exist in {os.getcwd()}")
  else:
      df = pd.read_excel(filename)
      print("File read successfully!")
  

If none of these work, sharing your full code snippet and the output of os.getcwd() would help narrow down the issue further.
