Why CodeViewIt
Free HTML editor with search for large text blocks
CodeViewIt is for anyone who needs to search in code online, especially long HTML files, minified markup, or huge pasted text blocks that other browser editors make painful to navigate. Edit with syntax highlighting, find text instantly, and preview live without installing anything.
Search in large text blocks, built in
Most online HTML editors and code viewers let you paste and preview, but they leave out proper in-editor search. If you work with large single-file pages, exported templates, log snippets, or documentation pasted into one buffer, scrolling manually is slow and error-prone.
CodeViewIt includes a dedicated search bar above the editor. Type a word or phrase, press Enter, and jump through matches with highlighted lines and a match count. That is ideal when you need to find text in a large file or search a long HTML document in the browser.
- Search across entire pasted blocks. No file upload to our servers.
- See how many matches exist before you navigate
- Highlighted lines so you spot results in dense or minified code
- Paste from clipboard into search to look up strings copied elsewhere
