Clean Google Sheets™ Data
Google Sheets™ is great for sharing and terrible at cleanup. Export, clean here, and paste back into a tidy sheet.
The goal is what comes after the cleanup. Catch issues now so the report, import, submission, or handoff can keep moving.
Whatever needs to happen next, messy Google Sheets™ data should not be the reason it stalls. Upload once and preview what CTS would clean before anything changes.
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 $4.99.
Drag & drop your file or screenshot, or browse
Accepts .xlsx, .xls, .csv, .png, .jpg, and .pdf · up to 50 MB
Tip: upload the actual spreadsheet file, not Excel temporary files that start with ~$.
Free scan + cleaned sample. No charge to preview.
No signup. Original file unchanged. View Trust & File Handling
On mobile, screenshots and CSVs work best. Larger Excel files are easier from desktop.

Built for
Built for people with something to finish, not a spreadsheet to babysit.
Analysts, bookkeepers, admins, operators, founders, and finance teams use CTS to get files ready for the send, import, merge, report, submission, or handoff that actually matters.

- Admins
- Operators
- Founders
- Finance teams
- Spreadsheet-heavy workflows
You do not need to diagnose the sheet before you can move forward. Upload the Excel or CSV file, review what CTS finds, and unlock only when the result helps you reach the next step.
CTS checks duplicate rows, blanks, spacing, inconsistent formatting, messy headers, dates, imported-data problems, and other things that can get between the file and its destination.
The spreadsheet is one step. Your goal is what comes next.
A finished report, successful import, clean handoff, or client-ready file is the point. Clean That Sheet™ helps with the repeatable cleanup step so you can get there without making spreadsheet repair your whole afternoon.

“We've found this tool to be a great fit for the kind of spreadsheet work we do at Lombard Toyota. It helps turn large, messy data exports into something much easier to read and work with, without requiring a lot of manual cleanup.
What we especially like is that it seems to understand the structure of dealership data instead of treating every column the same. That saves time and makes the finished spreadsheets much more useful for our day-to-day work.
Definitely a helpful tool for an automotive dealership working with a lot of data.”

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.
