Free Text Tools — Count, Convert, Slugify & Compare Online
Text Tools on Apex Toolz help writers, marketers, and developers manipulate plain text without opening heavyweight editors or uploading drafts to unknown websites. Count words and characters for essay limits, ad copy caps, and metadata length checks. Convert casing for titles, constants, and database seeds.
About this category
Sorting, deduplication, find-and-replace, and diff utilities clean messy exports from spreadsheets, logs, and CMS paste errors. Text to Slug creates URL-safe hyphenated paths for blogs and products. UUID Generator and Regex Tester support development fixtures and validation rules beside prose tasks.
Everything runs client-side — your manuscript, ticket payload, or customer list stays in the browser tab until you copy results intentionally. That matters for support logs, unreleased marketing copy, and HR snippets.
Text Tools pair naturally with SEO Tools (slug and SERP length), Code Tools (JSON adjacent to regex debugging), and Security Tools (UUID beside password generation).
Featured utilities below cover the highest-traffic text operations; the full category lists every text tool on Apex Toolz.
Plain text remains the lingua franca between systems — CSV exports, log files, markdown drafts, and API payloads all pass through text utilities before they become structured data in Code Tools.
Accessibility and readability start with words: counting, casing, and diffing support editorial review when legal or compliance must approve customer-facing copy changes line by line.
Support macros and canned responses benefit from Character Counter when SMS or chat platforms enforce hard character ceilings — paste before sending to avoid truncation mid-sentence.
Why use these tools
Word limits for essays, ads, and meta descriptions fail silently until paste time — live counters catch overflow before submission.
ALL CAPS accidentals in API keys and env files cause maddening bugs — case converter fixes in one click.
Diff checkers turn “what changed between draft 3 and 4?” into reviewable output for legal and marketing approvals.
Local slug generation beats hand-typing permalink cleanup on every blog post.
Paragraph and sentence counters help poets, journalists, and ad writers hit structural briefs without exporting to Word.
Markdown Previewer closes the loop for developers writing docs in repo — preview before opening pull request.
Sentence Counter supports micro-copy limits in mobile UI toasts and push notification previews.
