Daniel’s XL Toolbox is a free, open-source add-in for the Microsoft® Excel® spreadsheet software that helps you to analyze and present data and increases your productivity. Its primary target audience are life scientists, but it has proven useful for humanities and industry as well.

Analyze data

Collect data using the formula builder and transpose wizard; analyze your data by one-way or two-way ANOVA, linear regression or correlation; generate histograms from multiple columns; use the Toolbox to stratify your data and allocate subjects to study groups.

Present data

Use the XL Toolbox to add custom error bars, apply chart designs with few clicks, add series, watermarks or annotations and do much more with your charts. When you are ready to publish your work, use the chart export feature to produce ready-to-submit TIFF files.

Be productive

The XL Toolbox enhances your workflow with keyboard shortcuts, automatic backups, worksheet management and much more.
Text/CSV file import and export features facilitate data exchange with other software such as R or gnuplot.
