FileDuel puts two files side by side and shows you exactly what changed — every added line, every deleted word, every modified cell. No guesswork, no scrolling back and forth manually.
Whether you're reviewing a contract redline, reconciling two Excel reports, tracking changes in a code file, or comparing scanned documents — FileDuel handles it in seconds.
