flags.xlsx

Solution

I used the python pandas to read the xlsx file. I used regex to extract all valid words. Then used for loop to look out for strings that doesn't start with "fake_flag" and is not a digit and found the flag.

Python Script

# import pandas lib as pd
import pandas as pd
import re

dataframe1 = pd.read_excel('/content/flags.xlsx')

for each in re.findall(r'\b[\w_]+?\b', dataframe1.to_string()):
  if not each.startswith("fake_flag") and not each.isdigit():
    print(each)

Output

Flag: pearl{h3ll_0f_4n_3xc3l}
