GridManager — Stop wasting hours cleaning Excel data manually

Hey Product Hunter! 👋

I built GridManager because I kept seeing the same problem everywhere — people spending hours every week doing the exact same manual work in Excel: fixing column names, removing duplicates, cleaning messy formats, reordering data.

Not because they wanted to. Because they had no alternative.

So I built one.

GridManager is a free Excel add-in (Office.js) that lets you:

• Reorder columns without copy-pasting

• Set validation rules that stick, keyed by column name

• Clean and normalize messy data in one click

• Save and replay your cleanup steps across different files

No macros. No VBA. No coding at all.

It works directly inside Microsoft Excel — just install it from the add-in store and you're ready in 60 seconds.

Why free? Because the people who need this most — small teams, operations managers, analysts at SMBs — are exactly the people who can't justify paying for another tool. I wanted to remove every barrier.

I'd love your honest feedback. What would make this actually useful for your workflow?
