TextArray vs Convert Case
Updated July 22, 2026
Convert Case is a single-purpose favourite: paste text, switch between upper, lower, title and sentence case, and copy it back. It is fast, familiar, and does that one job cleanly.
It is also ad-supported and built around case conversion with a few extras. TextArray does case conversion too — and several hundred other text operations — with no ads and in 18 languages.
Where Convert Case is strong
- Instantly recognisable for one task: changing letter case.
- No account needed, works in the browser.
- A mobile app for on-the-go conversions.
If case conversion is genuinely all you need, Convert Case is hard to beat for muscle memory. The moment the job grows — removing duplicate lines, sorting, find-and-replace, encoding, counting words for SEO — you are reaching for a second site. TextArray keeps case conversion and all of that under one roof.
There are no ads in the way, the interface is available in 18 languages, and every tool runs locally with a live tally showing exactly what changed. It also installs as an offline app, so the tools work without a connection.
