camelCase, snake_case, and kebab-case
camelCase, snake_case, and kebab-case compares those joins for JavaScript, Python, CSS, and SQL. It cites PEP 8, MDN's JavaScript code style, Google's JavaScript, Python, and HTML/CSS style guides, PostgreSQL's identifier rules, and Google's URL guidance. Worked lines show where those documents disagree with each other and with the developer case converter. The converter page keeps the button steps and the odd tokens.
Change case in Excel, Sheets, Word, and Docs
How to change case in Excel, Google Sheets, Word, and Google Docs walks through UPPER, LOWER, and PROPER, then Word's Change Case menu and Shift+F3, then Format, Text, Capitalization in Google Docs. The examples are the ones Microsoft and Google publish. Where a help page is silent, the guide says so. Text that is not already in those apps still goes through the converter.
Developer case converter
A separate page, developer case, converts text to camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, and dot.case. It runs in the browser. The article on that page covers how the split works, worked examples, and edge cases such as acronyms, numbers, and non-English letters. The four buttons on the home page are unchanged.
Deeper guides, less repetition
The home page section on when to use each case style is now a short pointer. The full decision map is When to use each case. Title Case rules, Sentence case vs Title Case, and Common uppercase mistakes were rewritten so each page owns one job. Title Case examples now match the converter: an apostrophe stays inside the word, so o'neil becomes O'neil until you edit it to O'Neil.
Changelog
This page. Each shipped feature and guide gets its own note, with the date it went out and a link to the page.
Guide dates
Every guide now shows a byline for Alpha Elite Digital, plus Published and Updated dates. The four guides and the guides hub were first published on September 30, 2026. Updated is October 16, 2026. That date covers the byline, this log, and the longer guide text shipped the same day. The guides still link to the converter.
Sitemap dates
Every URL in the sitemap now carries a lastmod date, so a crawler can see when a page last changed. Later edits update that date only for the pages that changed, and for this changelog.
