When working on automation workflow, it's often easier to work with CSV format because it's easy to use and easy to parse.

you can export xlsx file to csv too and play around with it.

for example you have line-separated data like

username;password;email
reakl yuki;qwerty;[email protected]

#!/bin/bash

# note
# you can use grep to count occurrences of each character in a string
# check total of non-exists and exists user with: grep -c '0' output_file.txt

email_file="emails.txt"  # File containing emails, assuming delimeted by CRLF
database="evaluasi"

# Loop through each email in the file
