What is Case Converter?

Case Converter rewrites the capitalisation of pasted text into a chosen convention: sentence case, Title Case, UPPERCASE, lowercase, camelCase, PascalCase, snake_case or kebab-case. It is used to normalise headings, fix accidental caps-lock text and translate human labels into code-safe identifiers.

How to use it

  1. 1Paste the text you want to re-case.
  2. 2Pick a target convention from the dropdown.
  3. 3The converted text appears immediately in the output panel.
  4. 4Copy the result back into your editor.

Features

  • Eight conventions covering editorial and programming styles
  • Title Case keeps common short words (a, of, the, and) lowercase unless they start the string
  • Programming cases strip punctuation and collapse whitespace into the chosen separator
  • Original text is never modified — conversion is one-way into the output panel

When people use it

Cleaning imported headings

Spreadsheets and legacy CMS exports often arrive in full caps. Sentence case restores something readable in one paste rather than retyping every row.

Naming variables from a spec

Copy a field label such as 'Customer billing email' straight from a requirements doc and convert it to customerBillingEmail or customer_billing_email.

Enforcing a style guide

Publications that mandate sentence case for headlines can normalise contributor submissions before they reach the editor's queue.
