Project Manager

Supply Chain Coordinator

Sales Operations Lead
I'm not technical, so I don't use code-based diff tools. But this visual Excel comparison feels intuitive. It aligns the rows perfectly even when data is slightly sorted differently. It's the easiest way to spot discrepancies in our regional sales data without needing complex formulas.
Freelance Auditor
We deal with client files that are constantly updated without version notes. Doing a manual Excel spreadsheet comparison used to take half a day. Now I upload the old and new files, and boom—every changed price or quantity is highlighted. It significantly reduces the risk of human error in my audits.
HR Administrator
Clients constantly send updated budget files without telling me what changed. I use ExcelCompare to screen every document immediately. It's better than native Excel features because I don't need to open the heavy desktop app just for a quick check. The synchronous scrolling keeps everything aligned perfectly.

Frequently Asked Questions about ExcelCompare
Have another question? Contact us at support@excelcompare.org
How does the Excel compare view work?
It's like "spot the difference" for spreadsheets. ExcelCompare shows your files side-by-side. When you scroll one, the other moves too. We highlight changes in color, so you see exactly what's different in seconds. It is a strictly visual Excel compare experience.
What if I added a new row in one file?
No problem. Standard tools often get confused by new rows. ExcelCompare is smarter. It detects inserted or deleted lines and realigns your data. This ensures your Excel compare results are accurate, not just a mess of false errors.
Is my data safe with ExcelCompare?
Yes. We don't store your files. Everything happens in your browser. Once you finish your Excel compare task and close the tab, your data is gone. We verify that no business data is kept or shared.
What file formats can I upload?
We support standard .xlsx and .xls files. You can also use .csv files. Whether you are checking financial reports or inventory lists, ExcelCompare handles these formats easily.
Why use this instead of opening two Excel windows?
Comparing windows manually is tiring and error-prone. ExcelCompare does the hard work for you. We auto-highlight differences instantly. You stop guessing and start fixing. It's a much faster and safer Excel compare workflow.
Can I compare large spreadsheets?
Yes. Our engine is built for speed. It handles thousands of rows smoothly. Since ExcelCompare runs in your browser, keeping other tabs closed can help it run even faster during a big Excel compare job.
Can I share the comparison results with others?
In the future, ExcelCompare allows you to generate a direct link to your comparison view. You can send this link to your team or even embed it on your website. Recipients can open the Excel compare view instantly without needing to upload the files again. For added security, you can also set an expiration time for the link.
Does it handle specific data types like dates or decimals?
We follow a strictly "What You See Is What You Get" rule. ExcelCompare treats every cell—whether it's a number, date, or text—as a simple text string. We focus on the content, not the cell formatting or background colors. This simple approach ensures your Excel compare experience is predictable, without being confused by hidden data types.
Do I need to install software?
Not at all. ExcelCompare lives on the web. No downloads, no plugins, and no risky macros. Just open your browser (like Chrome, Edge, or Safari) and start your Excel compare session immediately.
Is this tool hard to use?
It is designed for everyone. You don't need to be an Excel expert. Just drag and drop your two files. ExcelCompare handles the rest. It's the easiest visual Excel compare tool you will ever use.
