TextCompare

TextCompare is a free online diff checker that finds the differences between two texts, files or code snippets. Paste or drop two versions and it highlights added, removed and changed lines, with line, word and character-level modes and side-by-side or inline views. Options let you ignore case, whitespace or line endings, sort lines and drop empty lines. You can merge changes git-style and export the diff as PDF, spreadsheet or PNG. Beyond plain text it compares Excel, CSV, Word, PDF, images, lists, JSON, XML, SQL, YAML, HTML, CSS and source code. Everything runs locally in your browser: nothing is uploaded, no sign-up.
