All the tools for your spreadsheets

Comparar Hojas de Cálculo brings together in one place the tasks that take the most time when working with Excel, CSV and ODS files: comparing two versions of a file, merging several workbooks, removing duplicate or empty rows, converting between formats, reducing file size, repairing files that won't open and protecting them with a password. Each tool handles one specific task and works in your browser, with no account and nothing to install.

The tools are designed for people who work with data every day: students and teachers, accountants, administrative staff, analysts and small businesses. You can use them, for example, to check what changed in an inventory before sending it, to prepare a CSV for import into another program, or to open a file made in the latest version of Excel in an older one.

Besides the tools, our blog publishes practical guides in five languages on formulas, data cleaning, format conversion and good habits so you never lose your work. If a tool doesn't do what you need, or you're missing one, you can write to us from the contact page.
