Case Converter

Convert text between naming cases

The Case Converter transforms any text between the common cases developers and writers use every day: camelCase, snake_case, kebab-case, PascalCase, Title Case, UPPERCASE, lowercase, and more. Instead of hand-editing identifiers or headings one word at a time, you paste your text, pick a target format, and get a clean result you can copy straight into code or content.

How it works

The conversion runs locally in your browser with JavaScript. The tool splits your text into words — handling existing delimiters, spaces, and case boundaries — then rejoins them in the format you choose. Because nothing is uploaded, you can convert variable names, database columns, or private copy without any of it touching a server.

Practical use cases

• Rename variables to match a project's naming convention.
• Turn a label like User Profile into user_profile for a database column.
• Convert API field names between camelCase and snake_case.
• Normalize headings and titles for consistent casing.

When you are preparing URLs, the Slug Generator produces a URL-safe form, while the Word & Character Counter helps you check length. For sweeping edits across a block, Find and Replace pairs well with case conversion.

Private by design

All processing happens in-browser, so no data is uploaded and nothing is stored. The tool is free, needs no account, and works on every modern browser including mobile. Close the tab and your text disappears completely.
