About the Online Notepad++
A Notepad++ style editor that runs in your browser. Open plain text or source files in tabs, get syntax colouring for more than thirty languages, and use the editing basics you expect: find, find previous and next, replace, replace all, match case, whole word, regular expressions, go to line, undo and redo, line numbers, code folding, bracket matching and word wrap. Text tools sort, deduplicate, trim, renumber and change the case of the selection or the whole file. Save a single file back to disk or download every open tab as a ZIP. Everything is stored in your browser and auto-saved as you type.
