Tool usage guide
The Date Format Unifier is a powerful utility designed to standardize inconsistent date strings into a single, uniform format, making it easier to organize data, sync databases, or prepare reports.
Background
A global team submits sales logs with mixed formats like 'DD/MM/YYYY' and 'Month DD, YYYY'.
Problem
The database rejects the import due to inconsistent date formatting.
How to use
Paste the list of dates, set 'Input Format' to 'Auto-detect', and set 'Target Format' to 'YYYY-MM-DD'.
Outcome
All dates are converted to a clean YYYY-MM-DD format, allowing for a successful database import.
Background
An application log contains Unix timestamps that are difficult to read in a monthly performance report.
Problem

How to use
Input the timestamps, set 'Input Format' to 'Unix Timestamp', and choose 'YYYY-MM-DD HH:mm:ss' as the custom target format.
Outcome
The raw numbers are transformed into clear, readable date and time strings for the final report.
