🌐 Overview

IndiaMART Supplier Scraper Pro is a dual-mode tool for extracting supplier contact information from IndiaMART — India's largest B2B marketplace with over 7 million registered suppliers.

Whether you are a sales professional building lead lists, a procurement team sourcing vendors, or a researcher mapping the Indian manufacturing ecosystem, this tool automates the tedious work of manually visiting hundreds of supplier profiles.

Available as both a Chrome Extension (no setup required) and a Python CLI script (headless, scriptable).

✨ Features

Extension Highlights

• 🎨 Dark-theme popup (720px wide) with live stats dashboard
• 📊 Live data table — company, phone, email, location, CEO, employees
• 💾 Session persistence — data survives popup close via chrome.storage.local
• 🔔 Real-time activity log with timestamps
• ⚡ Zero external dependencies — self-contained XLSX generator bundled in

Python Script Highlights

• 🖥️ Headless Playwright — fully automated, no manual clicks needed
• 📍 State-by-state scraping — iterate across all Indian states
• 🔄 Retry logic — each supplier retried up to 3 times before skip
• 📁 Date-stamped Excel output — indiamart_suppliers_YYYY-MM-DD.xlsx
• 🎛️ CLI flags — --keyword, --states, --headful, --output, --delay-min/max

📊 What Gets Scraped

Phone coverage: ~70–90% when /enquiry.html page is accessible.

Email coverage: ~20–40% (IndiaMART often hides emails behind login).

🚀 Installation

Chrome Extension (Recommended)

1. Download this repository — click Code → Download ZIP and unzip it.
2. Open Chrome and navigate to chrome://extensions/
3. Enable Developer Mode (toggle in the top-right corner).
4. Click Load unpacked → select the indiamart-scraper folder (the one containing manifest.json).
5. The green IM icon appears in your Chrome toolbar.

Note: The extension works on any Chromium-based browser (Chrome, Edge, Brave).

🕹️ How to Use

Option A — Auto Search (Recommended)

1. Click the IM toolbar icon to open the popup.
2. Enter your keyword (e.g. home furniture manufacturer) in the Search field.
3. Optionally enter a Location — type or pick Indian state(s), comma-separated.
4. Click 🔗 Open Search Page — IndiaMART opens in a new tab.
5. Once the page loads, click the extension icon again.
6. Press ▶ Start Scraping.
7. Watch the live log and stats update in real time.
8. When done, click ⬇ Export Excel to download a dated .xlsx file.

Option B — Manual Navigation

1. Navigate directly to any IndiaMART search results URL, e.g.: https://dir.indiamart.com/search.mp?ss=steel+pipes&v=4&cq=Maharashtra
2. Scroll down to ensure supplier cards are visible.
3. Click the extension icon → ▶ Start Scraping.

UI Controls

📞 How Phone Numbers Are Extracted

The scraper uses a robust multi-strategy extraction pipeline:

1. Primary: Fetch /enquiry.html for each supplier URL.
2. Parse the HTML and look for #footerPNS or data-pnsno attributes — IndiaMART's known phone number containers.
3. Fallback to a[href^="tel:"] links in the page.
4. Fallback to known CSS class selectors: .cust_ph_no, .mobtxt, [class*='callnumber'], [class*='phone_no'], etc.
5. Last resort: regex scan for 10-digit Indian mobile patterns ([6-9]\d{9}).
6. Retry: Each supplier is retried up to 3 times with exponential back-off before being skipped.

🐍 Python Version

A standalone Python script is included in the PY/ folder for users who prefer a CLI workflow or need to run scraping in a scheduled / headless environment.

Prerequisites

pip install playwright openpyxl
playwright install chromium

Usage

# Scrape a keyword across specific states
python PY/indiamart_scraper_py.py \
  --keyword "home furniture manufacturer" \
  --states "Delhi,Maharashtra,Gujarat"

# Watch the browser (non-headless)
python PY/indiamart_scraper_py.py --keyword "steel pipes" --headful

# Custom output path and delays
python PY/indiamart_scraper_py.py \
  --keyword "textile machinery" \
  --output /tmp/textile_leads.xlsx \
  --delay-min 3 \
  --delay-max 7

CLI Flags

🛡️ Anti-Ban Protection

Both the extension and Python script implement polite scraping practices:

• ⏱️ Randomised delays of 2.5–5 seconds between each supplier request.
• 🔄 Retry with back-off — failed requests are retried up to 3× before skipping.
• 🌐 Human-like HTTP headers: Accept-Language: en-IN,en;q=0.9,hi;q=0.7 and Cache-Control: no-cache.
• 🍪 Session cookies respected — credentials are included so IndiaMART recognises a logged-in session.
• 📄 Only /enquiry.html fetched — the minimal required page, not the full profile.

IndiaMART rate-limits aggressive bots. Stick to the default delays to avoid temporary IP blocks.

🔧 Requirements

Chrome Extension

• Google Chrome 88+ (or any Chromium-based browser supporting Manifest V3)
• An active IndiaMART session helps improve phone / email coverage

Python Script

• Python 3.8+
• playwright (pip install playwright)
• openpyxl (pip install openpyxl)
• Chromium browser installed via playwright install chromium

❓ Troubleshooting

Keep the browser tab open and in the foreground while the extension is scraping — Chrome may throttle background tabs.
