FAQ

Diff Checker

What types of content can I compare with Diff Checker?
DevME's Diff Checker works with any plain text: source code, configuration files, JSON, markdown, SQL queries, API responses, or prose. It highlights added, removed, and modified lines with standard diff color coding.
Does the comparison show word-level or line-level differences?
DevME shows both: line-level differences with standard red/green coloring, and within changed lines, the exact words or characters that differ are highlighted for precise identification.
Can I compare JSON or structured code files?
Yes. Paste JSON, code, config files, or any text. For structured JSON comparison, format both inputs with DevME's JSON Formatter first to normalize whitespace and indentation before running the diff.

Most free tools make money by processing and analyzing the contents of your files. We don't. DocsMe was built with local document processing as a first-class feature, not an afterthought.
