Frequently Asked Questions

Is this text diff checker free?

Yes — 100% free, no sign-up, no limits. Paste your texts and compare instantly in your browser.

What file formats can I compare?

You can drag and drop TXT, Markdown, JSON, XML, HTML, JavaScript, TypeScript, Python, CSS, SQL, Word (.docx), Excel (.xlsx), PowerPoint (.pptx), and PDF files. The tool extracts the text and compares it instantly.

Does it support code comparison with syntax highlighting?

Yes. Enable 'Syntax: ON' and the tool auto-detects your programming language (JavaScript, TypeScript, Python, JSON, HTML, CSS, SQL, Bash) and highlights keywords, strings, and comments in color.

Can I compare JSON or HTML files and ignore whitespace differences?

Yes. Tick 'Ignore whitespace' and the tool treats all whitespace — including newlines — as equivalent. A minified JSON and a formatted JSON with the same data will show as identical.

Can I merge changes and export the result?

Yes. Use the 'Keep original' / 'Take modified' buttons per hunk to accept or reject each change, then copy the merged result or export the full diff as a PDF with one click.
