Google Map data extractor: which kind of map data do you mean?

What does a Google Map data extractor do?

Lead Finder is a desktop extractor for one specific kind of map data: the public business listings shown on Google Maps, exported as spreadsheet rows. The phrase itself is ambiguous and attracts three different needs. Extracting business listings, names, phones, addresses and websites for sales or research, is what this page and this product address. Extracting your own saved places, labelled locations or location history is a different job entirely, handled by Google Takeout rather than by any third-party tool. Exporting a custom map you personally built, with your own pins and layers, is a third job handled by Google My Maps, which exports KML or KMZ directly from its own menu. Choosing the wrong one wastes considerable time, so the distinction is worth settling first.

Your own saved maps and places

Anything tied to your Google account, saved places, labelled locations, lists you created, location history and timeline data, comes out through Google Takeout. Select the Maps sections, choose a format, and Google emails a download link. No extraction software is involved and none would help, because the data is private to your account rather than published on the map.

This is the most common mismatch behind the phrase. Someone searching for a map data extractor frequently wants their own places back, and a business listing extractor does not do that and cannot be made to.

Custom maps you built yourself

A map you assembled in Google My Maps, with your own pins, layers and imported data, exports natively. The My Maps interface offers KML or KMZ download from its own menu, which opens in mapping software and converts to other formats easily.

That path covers geographic work: territory boundaries, route planning, site analysis. It has nothing to do with extracting businesses that Google itself lists, which is the third and entirely separate job.

Public business listings

This is the job that needs a tool, because Google offers no bulk export of other businesses listings. The information is public and visible to anyone, but there is no download button, so software reads what the map displays and writes it to rows.

Because a single search returns roughly 120 results whatever the true count, thorough coverage requires dividing the area into cells, searching each separately and merging with duplicates removed on place ID. That mechanic is what separates a tool from a manual copy-paste exercise.
