Remove Empty Columns from a Spreadsheet
Most exports come with columns nobody asked for. Clean That Sheet™ drops the empty ones so the file is only what you actually need.
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, empty columns 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.

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.”

Spreadsheet exports almost always include columns that don't contain anything useful, empty columns from a wide template, columns reserved for fields that nobody filled in, padded columns added by an ETL job, or remnants from a previous version of the export. Scrolling past them gets old, especially when the file is wide. Clean That Sheet™ drops the empty columns automatically so the file is narrower and easier to read.
We detect columns that are entirely empty as well as columns that only contain whitespace or placeholder values. The remaining columns keep their original order and their original headers. The data inside doesn't change, we're trimming the file, not reshaping it.
This is the fastest fix for a spreadsheet that's been through too many tools. Exports from CRMs and analytics platforms often include 30+ columns when you only need 8, and stripping the empties makes the file dramatically easier to work with in Excel, Google Sheets™, or anything you import it into next. It also makes file sizes smaller, which matters when you're emailing reports around.
Upload your .csv, .xlsx, or .xls file. Clean That Sheet™ shows you a preview of the cleaned file with the empty columns removed and tells you how many were dropped. If the preview looks right, pay only to unlock the full download in the same format. No subscription, no row caps, no signup.
Pair this with our blank row remover and trim-spaces tools and you've got a sheet that's exactly the size of the data inside it, no empty space, no padding, no padding-of-padding.
