Case converter
Convert text between camelCase, snake_case, kebab-case and the rest.
Rename a column, a variable or a file to whatever convention the code around it uses. The part most converters get wrong is acronyms: parseHTMLDocument is three words, not two, so it becomes parse_html_document rather than parse_h_t_m_l_document. This splits on the boundary before the last capital of a run, which is the rule that gets that right.

Frequently asked questions
- Does it handle acronyms properly?
- Yes. getURLPath becomes get_url_path, not get_u_r_l_path. A run of capitals is treated as one word, with the boundary before its last letter where a new word begins.
- Will it work on a whole list at once?
- It converts the text as one string, so a list of names becomes one converted name. For a column of values, convert them one at a time, or use snake_case on the whole line if the separator survives.
- Does Cyrillic work?
- Splitting relies on Latin capitalisation, so Cyrillic text stays as it is apart from spacing and upper or lower case. Mixed text keeps the Cyrillic and converts the Latin.
