Η by clicking here Diffnow offers free and online comparison between two files, texts or urls.
Imagine having two big ones archives that you want to compare. It could be, for example, lists of members of an association from two different years or two editions of a text document. And you want to find the differences easily and quickly and of course for free.
If the files are small, it may be quite simple to do manually, but when they are large the task may seem daunting. There are a whole host of file comparison tools in the world of computers that can do the job for you. They are usually called "diff" programs and are truly integrated into Windows and Mac OS. On a Mac all you have to do is open a terminal window and type: diff file-1 file-2 (where file-1 and file-2 are the files you want to compare).
On a Windows computer you should open a command prompt and do the same, but replace the diff command with the FC command (which means File Compare - compare file): fc file-1 file-2
Before you get excited, we have to tell you that the results from these built-in command line tools are not easy to read.
Fortunately, there are many available review tools available on the internet, which are also free and easy to use, and produce results that are much more comprehensible.
One of them is DiffNow which can compare not only Office documents (doc, docx, xls, xlsx, ppt, pptx) but also PDF, HTML, plain text and many other file formats.
Usage is simple. Go to https://www.diffnow.com/ and copy and paste or upload the two files you want to compare. Press the "Compare" button and you will see a screen with two windows, with the contents of each file displayed in each window, and with two-way differences highlighted in color. The results can be obtained if you wish.
The service is free for up to five comparisons per day and for files up to two megabytes. More comparisons and / or larger file sizes can be addressed by subscribing and / or subscribing to their paid service.
This site is something you may only need occasionally, and it's another free service, available online, without having to buy or install a niche program to do the job.
