Convert XLS to RTF

Fast, free, and secure XLS to RTF conversion. No registration required.

Whether you have one xls file or fifty, converting them all to rtf takes just seconds with Xonvert's browser-based engine. Your source file uses Excel 97-2003 encoding (standard since 1997). The output will use Rich Text Format encoding (available since 1987). This particular format pair is popular among office workers and students who need reliable, fast conversion. The entire conversion pipeline runs in a sandboxed WebAssembly environment for maximum security and performance.

Advantages of RTF over XLS

There are strong reasons to convert XLS to RTF:

Industry standard: In many document workflows, Rich Text Format has become the go-to format, making this conversion a frequent necessity.

API and automation: Many automated workflows and APIs expect Rich Text Format as input, making this conversion necessary for programmatic processing.

Editing flexibility: Rich Text Format files can be opened in a wider range of editing software, giving you more options for further modifications.

Collaboration ease: Team members and collaborators are more likely to have software that opens Rich Text Format natively, reducing compatibility friction.

Smaller file size: Efficient compression in Rich Text Format often produces significantly smaller files than Excel 97-2003, saving storage space and bandwidth.

XLS to RTF: Quality Comparison

Rich Text Format is known for basic formatting (bold, italic, tables) with broad application support. This means your converted output will benefit from Rich Text Format's core strengths. Meanwhile, the original Excel 97-2003's advantage of backward compatibility with Excel 97 and later may not fully carry over, depending on Rich Text Format's capabilities. Artifacts — unwanted visual or auditory imperfections — are minimized through Xonvert's tuned encoding parameters. Since Rich Text Format is lossless, no artifacts are introduced during conversion. Both formats are lossless, ensuring zero quality difference between input and output.

Document conversion from Excel 97-2003 to Rich Text Format involves translating formatting, layout, fonts, and embedded content between document models. Complex formatting like tables, headers, footers, and page breaks are mapped as accurately as possible. Some format-specific features (macros, track changes, advanced styles) may not have direct equivalents in the target format.
