Option A — Auto Search (Recommended)

  2. Scroll down to ensure supplier cards are visible.
  3. Click the extension icon → ▶ Start Scraping.

UI Controls

Button Action
▶ Start Scraping Begin scraping the active IndiaMART search tab
🔗 Open Search Page Build and open a search URL from the keyword/location inputs
⬇ Export Excel Download all scraped data as a .xlsx file
✕ Clear Wipe all data from the table and storage

📞 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
Enter fullscreen mode Exit fullscreen mode

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
Enter fullscreen mode Exit fullscreen mode

CLI Flags

Flag Default Description
--keyword required Search term (e.g. "steel pipes")
--states all states Comma-separated Indian states to search
--headful off Show browser window while scraping
--output auto-dated Custom Excel output path
--delay-min 2.5 Minimum seconds between suppliers
--delay-max 5.0 Maximum seconds between suppliers

🛡️ 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

Problem Solution
"Cannot connect to page" error Refresh the IndiaMART tab and click ▶ Start Scraping again
Extension popup is blank / not loading Go to chrome://extensions/, remove and reload the extension
Phone numbers showing — IndiaMART's page structure may have changed — open an issue
Export button is greyed out Start scraping first; the button enables after the first result
0 suppliers found Make sure you are on a dir.indiamart.com search results page
Python: playwright._impl._errors.Error Run playwright install chromium to install the browser
Rate limited / CAPTCHA Increase --delay-min and --delay-max values in the Python script

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