About Underscores to Spaces
Underscores are common in variable names, filenames and database fields, but they are hard to read as prose. This tool swaps every underscore for a space so identifiers like first_name or my_file_name become readable phrases. For full title formatting, pair it with the capitalize-words tool. It runs entirely in your browser, keeping your text private.
FAQ
Does it capitalise the words too?
No — it only swaps underscores for spaces; use the capitalize-words tool to title-case the result.
Will it touch hyphens?
No, only underscores are replaced; hyphens and other characters are left as-is.
Is it good for filenames?
Yes — it turns underscore_filenames into readable labels in one step.
