I built a set of free tools !!!

#webdev #javascript #python #productivity

Here's what's available right now:

1. 📧 Email & Phone Scraper

Paste a list of website URLs, get back emails, phone numbers, and Facebook links — automatically.

What it does:

Scrapes the homepage and the contact page of each URL
Decodes CloudFlare-protected emails (data-cfemail)
Bypasses basic bot protection (curl_cffi Chrome impersonation)
Returns a clean table you can export

Why I built it:
Most scrapers break on Wix/Squarespace sites or miss +33 formatted phone numbers. This one handles split spans, JSON-LD structured data, and obfuscated mailto links.

Free limit: 10 URLs/day — more than enough for prospecting.

2. 🌍 IP Geolocation Tool

Enter any IP address and get detailed info: country, city, ISP, ASN, timezone, VPN/proxy detection.

What it does:

Detects your own IP automatically
Shows an interactive map pinpointing the location
Identifies VPNs, Tor exit nodes, and datacenter IPs
Copy/export results in one click

Useful for debugging regional issues, verifying CDN routing, or checking if a user is behind a proxy.

3. 📊 JSON / CSV → Excel Converter

Upload a JSON or CSV file, get a formatted .xlsx back instantly — in the browser, no server upload.

What it does:

Handles nested JSON (flattens it automatically)
Preserves column types (numbers stay numbers)
Works entirely client-side — your data never leaves your machine

Great for quick data prep before sending to a non-technical client.

4. 📱 QR Code Generator

Generates QR codes for URLs, plain text, emails, phone numbers, WiFi credentials, and vCards.

What it does:

Custom colors and background
Adjustable size and error correction level
Download as PNG instantly
