New in ExamDiff Pro 17
Full version history
See what really changed in Word, Excel, and PowerPoint files
Rewritten Office support keeps tables, lists, comments, and footnotes, so you compare what the document says, not a flattened text dump.
How Office comparison works
Large files and folders stay fast
Comparing and merging is significantly faster and uses less memory. Folder comparison adds a tree mode and quick byte-by-byte checks.
Everything new in version 17
Crisper text, richer syntax styles
A new DirectWrite rendering engine draws sharper text, supports bold and italic syntax styles, and looks right on high-DPI screens.

Testimonials
More testimonialsI downloaded about 10 file-compare utilities and tried the lot. They all either crashed, displayed garbage, or stated there were no differences between the two files... Except for ExamDiff Pro, which was the ONLY utility able to correctly handle the two files. So I registered it on the spot.
We have been using this magnificent tool for several years. Almost every day it helps us solve our daily tasks very efficiently with minimal effort. ExamDiff is one of the best comparison utilities on the market, if not THE best.
ExamDiff Pro remains the best file comparison tool I've used. This tool has saved me hours of work and ensured that the changes I make are accurate.
