Frequently asked questions

What's the difference between camelCase and PascalCase?

camelCase starts with a lowercase letter (e.g. myVariable), while PascalCase starts with an uppercase letter (e.g. MyVariable).

When should I use snake_case?

snake_case is common in Python variable names, database column names, and file names — anywhere underscores are preferred over spaces.

Can I convert multiple lines at once?

Yes — the converter processes your entire input, including line breaks, in one pass.

Update history

  • 2026-08-30 Added: a cover image — used as the card thumbnail, social share image, and blog title image.
  • 2026-08-29 Fixed: Embed button now works (it silently did nothing before — Astro module scripts made document.currentScript unreliable) and the generated iframe snippet points at the correct /embed/{category}/{slug} URL instead of a 404. Removed: "API" share button — it linked to /api/v1/{slug}, which doesn't exist on this static site and always 404'd. Will return once a real API is built.
  • 2026-08-28 Added: linked blog post comparing this converter to a popular alternative.
  • 2026-08-28 Improved: title-row share bar (copy link, native share, X, Facebook) now shown on every page.
  • 2026-08-28 Fixed: full mobile responsiveness pass (result rows now stack cleanly on narrow screens).
  • 2026-08-27 Launched: 8 simultaneous case conversions shown side by side, no need to pick one at a time.
