This Is Your Monday Morning.

📊
The Manual Hell

You open a spreadsheet with 10,000 rows. Half the emails are broken. Dates are in 5 different formats. Phone numbers have random spaces. You sigh and start cleaning. Manually. Again.

💸
The Expensive Alternative

You Google "data cleaning tool" and find Alteryx. $433/month. Tableau Prep? $70/month. Your boss says "just use Excel." You die a little inside.

😰
The Trust Problem

You finish cleaning. But did you miss something? Row 4,847 has an invalid postal code. Row 7,203 has a duplicate. You won't know until your report is wrong and someone notices.

🔄
The Groundhog Day

Next week, same spreadsheet, same mess, same process. You clean the same columns the same way. Every. Single. Week. There has to be a better way.

There is.

Meet Excel Validator.

The Rules You Need, Suggested Automatically.
