Sheets works like any other spreadsheet. However, because it’s a cloud-based service, by default, it saves your work in near-real-time and stores your files in your Google Drive. You must log in with a Google account to create new spreadsheets, but once logged in, the tool is free to use. Sheets is a cloud-based service that supports real-time collaboration and document sharing features that desktop-based solutions generally cannot match. It works with the same file types as nearly every version of Microsoft Excel, including the XLSX, XLS, and CSV formats. You can open these common file types and save to these file types. This free spreadsheet software supports more than a hundred formulas for working with data. Also, OpenOffice Calc allows different toolsets to be detached from the main program window to provide more space for working while providing tons of useful features. The Extension Manager lets you add features to OpenOffice Calc that aren’t included in the default program, which is another way to customize the program to your liking. Microsoft Excel 2003 and 2007 formats are supported, and data can be imported from a text file and then filtered in Gnumeric. Files save to your computer in many formats, including XLS, XLT, PXT, CSV, and BMP. Spread32 is portable, which means you don’t have to install it to use it. Also, it can run from portable media like a flash drive. It takes up less space than the other programs in this list; the size is under a few megabytes. Files save to formats like XLS and CSV but also to some Accel-specific ones like VTS and ATP. SSuite Accel connects to external database files and supports opening files directly from Dropbox and other online storage services.
