How it works
Paste your text
Type, paste or open text with underscores. Nothing leaves your browser.
Choose a replacement
Swap runs of underscores for a space, a hyphen, or delete them.
Copy readable text
Underscores are replaced live. Copy the result or download it as a TXT file.
Humanizing snake_case
Runs of underscores are treated as one separator, so user__profile_name becomes a single gap instead of several. Space produces normal readable words, Hyphen produces kebab-case slugs for URLs and file names, and Nothing joins the parts into one token.
Leading and trailing underscores are replaced like any other, so _private becomes private with Space. The tool only touches the underscore character and never alters letters, digits or hyphens already present.
Filenames and pasted code
Use it to turn database columns, variable names and downloaded file names into titles for documents and slides. Code such as MAX_RETRY_COUNT reads instantly once underscores become spaces, and slugs such as my_post_title are one click away.
The summary counts every underscore removed so you can confirm the change. For mixed names containing both underscores and dashes, run this tool first and then tidy any remaining dashes by hand.
Private by design
Replacement runs entirely in your browser with no server, queue or account. File lists, code and private notes never leave your device and disappear when you close the tab.
There is no upload, no history and no watermark: open the tool, clean your underscores, copy or download the result and you are done. Only the app itself may be cached for offline use, never your text.
Questions
Is my text uploaded?
No. Underscores are replaced inside your browser. Your text never leaves your device.
What happens to double underscores?
A run like __ is replaced with a single space, hyphen or nothing, so words stay evenly separated.
Should I use a space or a hyphen?
Use a space for readable titles and a hyphen for URL slugs and file names. Nothing joins the parts into one word.
Is it free?
Yes. Free to use with no sign-up, no watermark and no daily limits.
