Text transformation tools take an input string and produce a transformed output — nothing more dramatic than that, but they cover the small operations that come up constantly when editing prose, code, or data. Renaming variables, sorting a list, cleaning HTML out of pasted content, switching between case conventions: each one is a five-second job once you have the right tool open.
The case converter handles eleven conventions in one tool (lowercase, UPPERCASE, Title Case, sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, dot.case, path/case) with intelligent splitting that handles acronyms (HTMLParser becomes html-parser, not h-t-m-l-parser). The sort lines tool offers four sort modes (alphabetical, natural for files like file2/file10, numeric, by length) with optional dedup, blank-line removal, and case-insensitive sorting.
The find and replace tool covers plain and regex modes with whole-word, case-insensitive, and multiline options. Match positions show before you commit to the replacement so you can verify the regex matches what you intended. The strip HTML tags tool drops markup entirely (script and style block content included), with options to preserve paragraph breaks and decode HTML entities.
