Text Toolbox

Features

Text Toolbox is a free online text-processing toolkit that wraps compare, case conversion, formatting, and text cleanup utilities into a single, side-by-side workspace. Paste one or two blocks, pick a tool from the tab bar, and get instant results for diffs, case flips, whitespace cleanup, quote handling, and more — without installing any editor extensions. Every string transformation stays in your browser and never touches a remote server.

When You Need This

Common pain points this tool solves

1. Running a line-by-line diff between two config files, SQL snippets, or legal contract versions to see exactly what changed
2. Standardizing case, indentation, and quotes across dozens of ad-copy or translation strings before feeding them into a CMS or i18n pipeline
3. Cleaning up messy OCR output, pasted email text, or code snippets with extra whitespace, smart quotes, and invisible control characters

How to Use

Step-by-step instructions

1. Open the tab for the task you need: text compare, case convert, format/cleanup, or one of the other built-in utilities
2. Paste one or two input blocks depending on whether the tool needs a single source or two sides to compare or merge
3. Tweak the options (case style, whitespace rules, quote normalization, show-only-diffs) and preview the result as changes update live
4. Copy the transformed output or download the full result as a .txt file for your workflow

Why Choose Korelyy

What makes us better

1. One browser tab replaces multiple niche desktop tools for compare, case, and formatting tasks — great for locked-down work laptops where installing utilities is blocked
2. Live multi-pane diff with line numbers and inline highlights, so contract, config, and i18n reviewers catch subtle wording changes instantly
3. All transformations run locally; copy containing passwords, API keys, PII, or unreleased product copy never leaves the device

Monetize With This Tool

Turn this tool into a side income stream

1. Use this tool to speed up your freelance work and take on more paying clients
2. Create polished content faster for your blog, YouTube channel, or social media and grow your audience
3. Offer this tool's capabilities as a service on Fiverr, Upwork, or to your local business clients

Frequently Asked Questions

1. Can I side-by-side compare two long texts and see only the lines that changed?

   Yes. The compare tab runs a line-based diff and can show unified or split view, highlight intra-line character changes, and filter out unchanged lines so you focus on deltas when reviewing contracts, i18n files, or pull request descriptions.

2. Which case conversions and formatting helpers are included?

   The case tool covers UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, kebab-case, snake_case, and capitalization toggles. The formatting tab adds whitespace trimming, quote normalization, tab/space conversion, line-break standardization, and sorting and deduplication helpers for lists.

3. If I paste an API key or customer PII into the tool, does it get sent anywhere?

   No. Every diff, case flip, whitespace strip, and sort is implemented as pure string math inside the browser with no network dependency. Nothing is uploaded, logged, or cached server-side, so secrets and regulated data stay in your control.

4. Can I clean up weird smart quotes and hidden control chars copied from Word or PDFs?

   Yes. The cleanup tab normalizes curly quotes to straight quotes, strips zero-width spaces and soft hyphens, removes stray BOM markers, and can collapse extra runs of spaces and blank lines to a single canonical form that pastes cleanly into code and CMS editors.

5. Is there a way to sort and deduplicate a long list of lines?

   Yes. The format module has sort ascending/descending, sort ignoring case, remove duplicates, remove blank lines, and reverse order. You can chain them — for example dedupe → sort ascending → normalize spacing — then copy the final list in one click.
