Sometimes you just need to quickly peek inside a plain text, CSV, Markdown, or JSON file without opening it in a full text editor or spreadsheet application. This tool reads the file directly in your browser and displays its contents instantly.
Because it uses the FileReader API, the file never leaves your device — there's no upload step, which makes it fast even for reasonably large files and safe for content you'd rather not send anywhere.
Once the content is displayed, you can copy it straight into another document, email, or code editor with a single click.
Because everything runs locally in your browser, results appear instantly and nothing you type or upload is ever sent to a server.
Bookmark this page if you expect to use this tool regularly — it loads fast and behaves the same way every time, with no account needed.
This kind of task shows up constantly in everyday writing, coding, design, and admin work, which is exactly why a dedicated, focused tool saves so much back-and-forth.
A tool that does one job well, without a cluttered interface or unrelated features competing for attention, tends to be faster to use than a heavier all-in-one app.
