Key takeaways
The fastest way to get contact data for any business is to search Google Maps and capture the results with a free Chrome extension
Export the list as CSV, Excel, or JSON, then upload it to ChatGPT or point Claude Code at the file to score, clean, and segment leads
The extension is the means. The Vonsel dashboard is the end: a mapped CRM with review analysis and AI email per business

Contact data is the raw material, not the finish line
Every AI workflow that touches local businesses runs into the same wall first: you need real contact data. A model can score leads, write emails, and spot patterns, but only if you hand it a clean list of businesses with phones, websites, and addresses attached. Prompting an AI to "find me dentists in Miami" gives you guesses, not a database you can act on.
So the practical move is to separate the two jobs. First capture the data from a source that actually has it, which is Google Maps. Then feed that structured list to whichever AI tool fits the task. The scraper is the means, your AI is the analyst, and the outcome is a working list.
The Vonsel Chrome extension handles the first job. You search a business type and location on Google Maps, run the capture, and it pulls names, phone numbers, websites, addresses, categories, ratings, and more. Then it exports the batch as CSV, Excel, or JSON so any model can read it. This is the literal meaning of feeding your AI with data.

Step one
Capture the list and pick your export
Open Google Maps, type something like "law firms in Austin" or "coffee shops in Lisbon," and let the results load. Click the Vonsel pop-up and start the capture. The extension walks the listings and builds a structured record for each business, then lets you export in CSV, XLSX, or JSON.
Format choice matters more than people expect once AI enters the picture. Each one has a natural home, so match the file to the tool you plan to use next.
Format
Best for
Why
CSV
ChatGPT uploads, quick spreadsheet checks
Universally readable, small, easy to preview before prompting
Excel (XLSX)
Manual review, sharing with a team
Keeps formatting and multiple sheets, still parses cleanly in AI tools
JSON
Claude Code, Codex, local models
Structured fields a script or agent can read without guessing columns

Step two, path A
Feed the file to ChatGPT
For most people, ChatGPT is the fastest way to turn a raw list into something useful. Export your capture as CSV, open a chat, attach the file, and describe what you want. The model reads every row and works across the whole list, not just the part you can see on screen.
The trick is to prompt with intent. A vague "analyze this" wastes the upload. Instead, tell it exactly what job to do against your columns. Here are prompts that map cleanly to a business contact export.
Goal
Prompt to paste after the upload
Score and rank
"Rank these businesses by how likely they need a new website. Use rating count, presence of a website field, and category. Explain the top 10."
Clean and dedupe
"Remove duplicate rows by phone number, flag entries with no website, and return a clean CSV."
Segment
"Group these leads into three tiers by review volume and suggest a different opening line for each tier."
Draft outreach
"Write a short cold email for row 4 that references its category and city. Keep it under 90 words."
From here you can iterate: ask it to analyze the lead list further, or jump straight to writing cold emails from the scraped data. Because the file already contains phones and websites, the model has real anchors to personalize around instead of inventing details.
No data, no analysis
ChatGPT can only work with what you upload. Capture a real list first with the extension. Free to download, no trial and no credit card.
When your list gets bigger or you want repeatable output, a chat window starts to feel cramped. This is where Claude Code shines. It is an agentic coding tool that reads files on your machine, writes scripts, and runs them, so it can process a JSON export of thousands of businesses without you copying anything into a prompt box.
Export the capture as JSON, drop it in a folder, and open Claude Code there. Then describe the outcome in plain language and let it write and run the code.
Score at scale
"Read leads.json, add a priority score from the review count and website presence, and write the sorted result to scored.csv."
Build a dashboard
"Turn leads.json into a single HTML page with a map and filters by category and city." See building a lead dashboard.
Enrich and merge
"Match these businesses against my existing customers.csv and label the ones I already work with."
Automate the loop
"Write a script that ingests any new JSON export in this folder and appends it to a master list, deduped by phone."
The advantage is that the work becomes reusable. Once Claude Code writes a scoring script, you run it on every future capture. For a full walkthrough, see analyzing leads with Claude Code.
The pattern is always the same. The Chrome extension gets contact data for any business you can find on Google Maps. Your AI turns that data into a decision. The two are complementary, not competing, and neither works well without the other.
Other engines
Codex, local models, and everything else
ChatGPT and Claude Code cover most needs, but the same JSON or CSV export works anywhere. If you live in a terminal, Codex can enrich lead lists with the same script-and-run approach. If privacy matters or you process large volumes on a budget, you can run local LLMs against the lead data so nothing leaves your machine.
Because the extension follows the standard Chrome extension model and exports plain files, there is no lock-in on the AI side. Whatever model you prefer today, and whatever you switch to next year, the input is a clean file of businesses. That is the whole idea behind feeding your AI with business data.
The end goal
From a raw file to a working pipeline
AI analysis is powerful, but a scored CSV is still just a file. At some point you need to call the leads, track who replied, and see them on a map. That is the job the Vonsel dashboard does, and it is why the extension exists in the first place.
Inside the dashboard, captured businesses land in a mapped CRM. Review Intelligence reads the Google reviews and surfaces pain points, so you know a restaurant is getting complaints about wait times before you ever pick up the phone. Email Intelligence drafts an AI email per business grounded in those specifics. The result is a value added database, not a raw dump: contextualized with the exact angle that will land.

Feed your AI with real business data
Capture any list from Google Maps, export CSV, Excel, or JSON, and work it in ChatGPT or Claude Code. Free download. No trial, no credit card. Explore features or see the dashboard.
Open Google Maps, search for a business type and location, and run the free Vonsel Chrome extension. It captures names, phones, addresses, websites, and more, then exports the list as CSV, Excel, or JSON so you can feed it to any AI tool.
Which file format should I use to feed leads to ChatGPT or Claude Code?
CSV and Excel work well for quick analysis and prompts inside ChatGPT. JSON is better for Claude Code, Codex, and local models that read structured fields programmatically. The Vonsel extension exports all three, so you can pick per task.
Is the Vonsel Chrome extension free?
Yes. The Vonsel Chrome extension is a free download with no trial and no credit card required. It captures the business contact data, and the Vonsel dashboard adds the mapped CRM, review analysis, and AI email layer on top.
