## 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

```python
# 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)
```
