How to Compare Two Pieces of Text
Find the exact differences between two text snippets, code blocks, or configuration files using the DevHexLab Text Diff tool.
Tool Used
Text Diff Checker
Open the Text Diff tool
Navigate to /tools/text/text-diff.
Paste the original text on the left
Paste the first version of your text, code, log, or document into the left input area. This is the baseline that the second version will be compared against.
Paste the changed text on the right
Paste the second version of the same content into the right input area. The tool compares the two side by side.
Read the highlighted differences
Removed lines or characters are shown in red on the left. Added lines or characters are shown in green on the right. Unchanged lines stay neutral. You can quickly see what was added, deleted, or modified.
Switch between line and character diff
Use the toggle to switch between comparing whole lines and comparing character by character. Line diff is best for code and config files. Character diff is best for spotting small typos or rewordings inside a paragraph.
Copy the result or share
Use the copy button to grab the diff output, or share your screen with a colleague to review the changes together. Nothing is uploaded, everything stays in your browser.
All done!
You are ready to use Text Diff Checker like a pro.
