Convert text case for copy, code, and data cleanup
Use the text case converter to switch between uppercase, lowercase, title case, sentence case, capitalized words, inverse case, alternating case, camelCase, PascalCase, snake_case, kebab-case, and constant case.
It is useful for normalizing pasted content, preparing headings, converting variable names, or cleaning batches of labels before they move into code, CMS fields, or spreadsheets.
