Hurree— The smarter, simpler way to analyze your data
Quick way to do any calculations without leaving your browser tab. Spreadsheets are a powerful tool, but often you need just simple and quick results. Switching tabs and apps can be painful when doing research, so this why I have created a quick spreadsheet.
SheetHub turns your spreadsheets (either Google Sheets or Excel Online) into a REST-ful JSON API. It takes less than 2 minutes to signup and create your first project.
