Turn text into a variable name

100% local. Your text never leaves this browser tab.

Paste a label, heading or column name and get a valid code identifier: accents are folded, spaces and symbols become underscores, and only letters, digits and underscores remain. Perfect for variables, database columns and JSON keys.

What makes a valid name

Letters, digits, underscores

Only identifier characters

Everything outside letters and digits is dropped or turned into an underscore, giving a name a compiler or database will accept.

Accents folded first

Accented letters are transliterated to ASCII, so Café becomes Cafe rather than being removed.

snake_case output

Words are joined with underscores, the safe default for Python, SQL columns, JSON keys and environment variables.
