Clean Google Sheets Data
Google Sheets is great for sharing and terrible at cleanup. Export, clean here, and paste back into a tidy sheet.
Catch issues before they turn into a resend, failed import, or a question you have to answer later.
Upload your spreadsheet once. Clean That Sheet checks for messy Google Sheets data and other common cleanup problems, then shows you a free preview before anything is changed.
Free preview first. Full cleanup only if it helps.
Upload your file to see an issue summary, duplicate groups, blank rows, sample cleaned rows, and cleanup notes. If the preview looks useful, unlock the full cleaned file and change report for $4.99.

Google Sheets is where most teams actually keep their data, and shared sheets get messy fast. Different people enter the same customer three different ways. Copy-pastes from email bring trailing whitespace and weird formatting along for the ride. Imports from Forms or a connected tool drop in empty rows and inconsistent dates. Clean That Sheet is the cleanup step you can run on any of it without installing a Google Workspace add-on.
The workflow is simple. In Google Sheets, go to File → Download → Comma-separated values (.csv). Upload that file to Clean That Sheet. We'll remove duplicate and near duplicate rows, trim whitespace, drop empty rows, standardize emails and dates, and tidy column headers. Download the cleaned CSV and either import it into Google Sheets again or paste it directly back into the same tab over the messy data.
Why not an add-on? Add-ons need permissions to read your entire Drive, often have monthly subscriptions, and tend to do too much. Clean That Sheet is one focused tool that you don't have to grant any access to. The file you upload is processed and discarded, we never see the rest of your spreadsheet, your Drive, your Google account, or anything else.
This works especially well for collaborative sheets, customer trackers, sales pipelines, recruiting boards, content calendars, survey results, anywhere multiple people add rows and the formatting slowly drifts. Run the cleanup once a week, paste back, and the sheet stays usable instead of becoming the thing nobody wants to open.
Preview is free. Pay only to unlock the finished file. No subscription, no Google login, no follow-up.
