Traditional crosschecking new file versions against previous ones requires scrutiny and therefore multiplies human error. Need to quickly find differences between two Word documents? Learn how to compare DOC, DOCX, RTF and ODT files.
Why compare Word documents?
The comparison feature is important in the document workflow, when you need to find omitted or added symbols, words, sentences, and even paragraphs in larger texts without spending much time. Document comparison is especially popular in the following fields of expertise:
- Law & jurisdiction. Legal companies often deal with templates of contracts, agreements, memoranda, and other documents. New contracts are rarely created from scratch and therefore may look quite similar. Comparison helps employees keep every detail under control.
- Regulations. Whether government guideline or software usage policy, regulatory papers are subject to slight amendments or drastic changes. With the comparison functionality, officials need seconds to find differences between two versions.
- Education. Tutors can compare two Word docs to see, what students added or deleted from their papers and whether they have found all mistakes from the first version.
This list is not comprehensive — ideas of comparing documents are virtually unlimited. The feature is relevant for most industries and companies with electronic document workflow.
Document comparison: desktop vs. online
Today you will find numerous websites to compare text documents online, some of them are even free. That means you can detect differences in documentation easily and fast. Some benefits of this method include:
- Side-by-side view for checking what’s different in the same area of two files
- Time-saving approach for updating documents
- No additional software installations
- Cross-platform functionality
Online document comparison has at least two big disadvantages, though. In free versions, most online services will set limitations for a number of concurrent comparisons, file size, or just bombard you with ads. Free comparison websites also rarely care about security and how they handle your data is pretty much unclear. Uploading confidential documents may result in data loss and undermined reputation.
Pro versions usually unlock all capabilities, but the prices are rather high.
