Frequently Asked Questions

How does the string difference checker work?

The tool compares two strings and identifies the differences by analyzing them either word by word or character by character. It highlights additions, removals, and unchanged segments based on your selected settings.

Can I ignore case and whitespace differences?

Yes, you can enable the "Ignore case" and "Ignore whitespace" options to focus solely on meaningful content changes, disregarding case sensitivity and extra spaces.

What is the difference between unified and split views?

The unified view displays both strings in a single column with differences highlighted inline, while the split view presents the original and modified strings side by side for easier comparison.

Is there a limit to the string size I can compare?

The tool can handle large blocks of text efficiently. However, extremely long strings may take slightly longer to process. It's recommended to use the tool for strings up to several thousand characters for optimal performance.

Can I copy the comparison results?

Yes, after generating the differences, you can use the "Copy" button to easily copy the highlighted results to your clipboard for use in other applications.
