PasteGrid

PasteGrid turns messy copied text into a clean table you can copy as CSV, Markdown, or JSON. It runs fully in the browser and has no build step, account, tracking, or network dependency.

Live demo: https://bte808.github.io/fun-20260531-b-extra-paste-grid/

Small teams keep losing time between chat notes, link dumps, task lists, spreadsheet rows, and issue descriptions. Recent public product launches keep circling the same need: less app switching, faster lightweight spreadsheets, and cleaner structure from messy input. PasteGrid keeps that workflow local and simple.

Inspiration came from public browsing on 2026-05-31:

• Product Hunt's productivity category, where the framing centers on automating work and reducing switching: https://www.producthunt.com/categories/productivity
• HuntScreens listings around quick spreadsheets and messy-input structuring: https://huntscreens.com/en/products/quicksheet and https://huntscreens.com/en/products/dodoform
• Better Launch's small calculator/tool pattern for one focused workflow: https://betterlaunch.net/products/calcfi

Only the idea shape was borrowed. The code, UI, sample data, and copy in this repo are original.

• Paste CSV, TSV, pipe tables, semicolon tables, bullets, checklists, task snippets, URLs, emails, amounts, dates, tags, and key: value notes.
• Auto-detect table delimiters and likely headers.
• Extract common fields from loose text: item, owner, email, date, amount, URL, status, tags, and note.
• Preview the result as a table.
• Copy or download CSV, Markdown, or JSON.
• Copy a plain-language cleanup brief for issue comments, handoffs, and quick review notes.
• Keep the last local input in localStorage for quick retry.

PasteGrid is for the awkward moment before data becomes a spreadsheet, GitHub issue, CRM import, report table, or planning note. It is faster than opening a spreadsheet for tiny cleanup jobs, and safer than sending private notes to a hosted AI service for formatting.

• Local-first and dependency-free.
• One page, one job, no setup.
• Copyable brief makes the cleaned result easy to explain before sharing the table.
• Useful for operators, students, support teams, founders, and developers.
• Easy to fork because the parser is isolated in src/pastegrid-core.js.
• Works as a static GitHub Pages site.

npm test
npm run serve

Then open:

http://localhost:5178/

Because the app is static, you can also serve it with any local static server.

1. Paste messy text.
2. Keep Auto mode, or force CSV/TSV/Pipe/Semicolon/Loose lines.
3. Click Clean table.
4. Pick CSV, Markdown, or JSON.
5. Copy or download the result, or click Copy brief to share a short summary of what PasteGrid detected.

This repo includes a lightweight Node smoke test:

npm test

It checks the parser, output formats, static file wiring, mobile CSS breakpoint presence, README/license presence, and that no runtime dependencies were added. With a local server running, npm run verify:browser launches a temporary headless Chrome session and checks a desktop flow plus a 390 x 844 mobile viewport.

Local acceptance used:

• npm test
• python3 -m http.server 5178
• curl -I 'http://localhost:5178/index.html?v=20260531-b-extra-paste-grid'
• npm run verify:browser
• Desktop browser interaction
• 390 x 844 mobile viewport check

• Import from clipboard automatically after a permission prompt.
• Let users save reusable extraction recipes.
• Add column rename and hide controls.
• Add a small browser extension wrapper for selected text.
