What is Text Case Converter?
Fixing ALL CAPS email subjects, title-casing blog headings, or normalizing data exports — case changes are a daily text job. ToolYour Text Case Converter transforms pasted text into uppercase, lowercase, title case, sentence case, alternating case, and other modes without a spreadsheet formula.
Honest limits: Title case uses English-style rules — small words (a, the, of) may stay lowercase mid-title depending on the mode. Accented characters and non-Latin scripts follow Unicode case mappings where supported. The tool transforms text you provide; it does not fetch URLs.
Available in the browser, via REST (POST https://api.toolyour.com/api/v1/text-utilities/text-case-converter), and MCP.
