Text Comparison

Tool Introduction

The "Text Comparison" tool is an efficient and practical online text difference comparison tool. It helps users quickly identify and highlight all differences and similarities between two pieces of text, code, or documents. Whether for document proofreading, version iteration comparison, code review, or analyzing log file changes, this tool provides clear and intuitive comparison results, significantly improving your work efficiency and accuracy. It supports a variety of flexible comparison modes, designed to meet text comparison needs in different scenarios, making it your capable assistant for handling text differences.

How to Use

1. Copy and paste the first piece of text content you need to compare (e.g., old version document, code, etc.) into the "Text A" input box on the left.
2. Copy and paste the second piece of text content you need to compare (e.g., new version document, modified code, etc.) into the "Text B" input box on the right.
3. (Optional) According to your comparison needs, select the appropriate comparison mode, for example:
   • Line Mode Comparison: Compares line by line, suitable for documents and code.
   • Character Mode Comparison: Compares character by character, can find more subtle modifications.
   • Ignore Whitespace: Ignores differences like spaces, tabs during comparison.
   • Ignore Case: Ignores letter case differences during comparison.
4. Click the "Start Comparison" button on the page.
5. The comparison results will be clearly displayed in the area below. Deleted lines or characters are usually highlighted with a red background, newly added lines or characters with a green background, and modified lines will show specific differences on both sides.

Frequently Asked Questions

• Q: How large a text does this tool support for comparison?
• A: This tool is designed to handle regular-sized text content, theoretically supporting larger texts, but for optimal performance and user experience, it is recommended to keep the text size for a single comparison within a few megabytes.
• Q: What is the output format?
• A: The output results are intuitively displayed in HTML format on the webpage, highlighting differences with different colors. Users can directly copy the highlighted text or save it as a PDF using the browser's print function.
• Q: Can I compare texts with different encoding formats?
• A: It is recommended that you ensure both texts use the same encoding (e.g., UTF-8) before input to avoid misjudgments caused by encoding issues. The tool processes by character by default, but inconsistent encoding may affect result accuracy.
• Q: Will the original text's formatting be preserved during comparison?
• A: This tool primarily performs difference comparison on plain text content. Rich text formats (such as bold, italics, images, etc.) in the original text will be ignored during comparison, and only plain text content will be processed.

Notes

• To ensure the accuracy of the comparison results, please make sure to copy the complete text content to be compared into the corresponding input boxes.
• For texts containing a lot of spaces, tabs, or line breaks, you can try checking the "Ignore Whitespace" option to focus on the core differences in content.
• This tool does not store any of your input data. Your input content will not be retained after you close or refresh the page. Please pay attention to protecting personal privacy and avoid entering sensitive information.
• If the amount of text to be compared is very large, it may cause the browser to freeze or prolong processing time. Please wait patiently or try comparing in segments.
• When comparing code, please note that different programming language comment styles may affect the effectiveness of options like "Ignore Whitespace".
