Code Comparison

Tool Introduction

The code comparison tool aims to help developers and text editors efficiently compare the differences between two pieces of text or code. It intelligently identifies added, deleted, and modified lines and highlights them with intuitive colors, thereby greatly simplifying code review, version control, and document merging workflows. Whether comparing code snippets, configuration files, or plain text, this tool provides clear and concise difference analysis results.

How to Use

1. Paste or type the first text or code to be compared into the left input box.
2. Paste or type the second text or code to be compared into the right input box.
3. Click the "Compare" button, and the tool will automatically process and display the differences between the two texts.
4. The output results will be displayed in a side-by-side comparison (or inline comparison) format, with differences highlighted in different colors, making it easy for you to quickly locate changes.

Frequently Asked Questions

• Q: What input formats does this tool support?
• A: This tool is primarily used for comparing plain text content, so it supports input in any text format, including code in various programming languages, configuration files, log files, or ordinary documents.
• Q: What is the format of the output?
• A: The output is text with highlighted differences, usually displayed in two columns (left and right, or top and bottom), visually showing the differences. Added, deleted, and modified lines are distinguished by different colors, allowing users to quickly identify them.
• Q: Can I compare file content?
• A: This online tool primarily accepts copied and pasted text content. To compare files, please first copy and paste the file content into the corresponding input boxes for comparison.
• Q: How are differences highlighted?
• A: Typically, added lines are highlighted with a green background, deleted lines are highlighted with a red background, and modified lines will display the old content (red) and new content (green) on the left and right sides respectively, allowing users to clearly see the specific changes.
• Q: Is there a limit to the length of input text?
• A: To ensure a good user experience and browser performance, we recommend avoiding extremely large texts (e.g., over hundreds of thousands of characters). For particularly long texts, it may affect comparison speed or cause the browser to slow down.

Notes

• Please ensure that the content in the input boxes is the plain text you want to compare, avoiding mixing in images or other non-text data.
• This tool does not store any of your input data; all comparison operations are completed locally in your browser. Please feel free to use it.
• For text containing special characters or encoding, please ensure your browser can correctly parse and display it to avoid deviations in the comparison results.
• Although the tool will try its best to accurately identify differences, for very complex or poorly formatted text, it is recommended to carefully verify the results.
