Compare total cost of ownership
For many organizations, Row Zero offers a significantly lower total cost of ownership compared to using traditional spreadsheets when you factor in the infrastructure, workarounds, and human capital needed to empower teams to securely work with live data in spreadsheets.
With Row Zero
Security is default, data connectors are built-in, and anyone can truly self-serve large, production datasets. There is no middleware, no plugins, no giant backlog of data requests. Many customers eliminate their BI tools entirely or reduce licenses.
Without Row Zero
Teams use BI tools to stage data for exports to Excel, pay for plugins to connect Excel to data sources, and build out a complicated governance apparatus to try to keep data secure. Data teams have to keep building BI dashboards or create data extracts to help business teams operate and answer questions. The end result is a lot of expensive licenses and human resources for a legacy solution that still lacks the scale and security advantages of the cloud.

Frequently asked questions
The Excel maximum row limit is 1,048,576 rows. If you try to import a file larger than this, Excel will truncate the file at this row limit. Note, this is the maximum row limit. In practice, Excel may crash or slow down below this limit depending on your dataset and analysis.
Yes, Row Zero is a good replacement for Excel, especially for companies that need to work with big data in a spreadsheet or want to enforce modern cloud security for spreadsheets. Row Zero gives teams a secure alternative to Excel for big data. You can even import XLSX files into Row Zero.
Row Zero and Google Sheets are both good Excel alternatives. Row Zero is better for big data and security and Google Sheets is better for Excel compatibility and integration with Google Workspace.
Google Sheets and Excel online are similar spreadsheets. In fact, they are similar enough that you can convert basic spreadsheets from Excel to Google Sheets and vice versa without much issue. The biggest difference between Excel and Google Sheets is integration with other workspace tools - Excel 365 better integrates with Microsoft 365 tools like Powerpoint and Word and Google Sheets integrates better with Google Workspace (Google Docs, Slides, etc.). Excel desktop is a bit more different than Google Sheets, but both are similar.
Both versions of Excel have all of the core spreadsheet features like formulas, formatting, filter/sort, charts, and pivot tables. Excel online offers some additional features like real-time collaboration, cross-platform accessibility, link sharing, easier connectivity to other online tools, and cutting edge features like dynamic arrays and AI integration.
The best spreadsheet for you will depend on your needs. If you need big data power, data connectivity, or enterprise security, then Row Zero is a good alternative to Excel. If you want to seamlessly integrate with your existing workspace and don't need to work with big data, then Google Sheets may be a better Excel alternative.
