- Description
- An RTF file is a common text file format that supports "rich text." It includes several types of text formatting, such as bold type, italics, different fonts and font sizes, and custom tab settings. RTF files also support objects and images, such as .JPG and .PNG files, saved within the text file.
- An XLSX file is an Excel spreadsheet created by Microsoft Excel or another spreadsheet program, such as OpenOffice Calc or Apple Numbers. It stores data in worksheets, which contain cells arranged in a grid of rows and columns, and may also contain charts, mathematical functions, styles, and formatting. XLSX files are commonly used to store financial data and to create simple or complex mathematical models.
