Reverse Geocoding: Convert Coordinates to Street Addresses
Upload CSV with Lat/Long - Get Full Addresses Back
What is Reverse Geocoding?
Reverse geocoding is the process of converting geographic coordinates (latitude and longitude) into a human-readable street address. It's the opposite of regular geocoding, which converts addresses to coordinates. CSV2GEO is reverse geocoding software that makes this conversion simple and fast.
For example, if you have GPS coordinates like 40.7128, -74.0060, reverse geocoding tells you that's New York City, NY, USA. This is useful when you have location data from GPS devices, mobile apps, or sensors and need to know the actual address.
Most online reverse geocoding tools only handle one coordinate at a time. CSV2GEO handles batch reverse geocoding — upload a file with thousands of lat long pairs and get full street addresses back for every row. It's free for up to 100 lookups per day.
CSV2GEO offers two ways to reverse geocode: upload files through our web interface for quick batch processing, or integrate our API directly into your applications for automated lookups at scale.

How to Convert Latitude and Longitude to Address
Every coordinate pair on Earth corresponds to a physical location — a street corner, a building entrance, a stretch of highway. Converting latitude and longitude to an address means taking those raw numbers and resolving them to the closest known postal address in a global database. The technical term for this process is reverse geocoding, and it works by finding the nearest address point to your coordinates using spatial indexing across hundreds of millions of mapped locations.
If you have a spreadsheet full of coordinates — from GPS trackers, mobile devices, survey equipment, IoT sensors, or exported from another system — you need a tool that can match each coordinate pair against an address database and return structured results you can actually use. That means not just a string of text, but individual columns for street, city, state, postal code, and country, ready to drop into your CRM, database, or report.
Prepare Your File
Open your CSV or Excel file and make sure latitude and longitude are in their own columns. They can be labeled anything — "lat", "latitude", "y", "coord_lat" — CSV2GEO detects them automatically.
Upload & Confirm
Drag and drop your file onto CSV2GEO. A preview appears with your coordinate columns highlighted. Verify the selection or manually pick the right columns if your file uses unusual naming.
Run the Conversion
CSV2GEO matches each coordinate pair against 461M++ addresses across 39+ countries. Small files finish in seconds. Larger files process in the background.
Download Results
Your original file comes back with new columns appended: street number, street name, city, state, postal code, and country. Every row with valid coordinates now has a resolved address.
Example: You upload a file with two columns:
latitude: 40.748817 longitude: -73.985428
CSV2GEO returns: 20 W 34th St, New York, NY 10001, United States — parsed into six separate columns.
Understanding Coordinate Formats
Not all coordinates look the same. Before converting latitude and longitude to an address, it helps to know what format you're working with:
Decimal Degrees (DD)
40.748817, -73.985428
The standard format. Positive = north/east, negative = south/west. CSV2GEO uses this natively. This is what GPS devices and most modern systems export.
Degrees, Minutes, Seconds
40° 44' 55.7" N, 73° 59' 7.5" W
Often seen in older datasets or printed maps. Convert to decimal degrees before uploading — divide minutes by 60, seconds by 3600, then add to degrees.
Single Column Combined
40.748817, -73.985428
Both values in one cell, comma or space separated. CSV2GEO splits and processes these automatically — no need to separate them into two columns first.
When Results Are Approximate
Not every coordinate lands neatly on a building. A GPS point in the middle of a highway resolves to the nearest known address. A coordinate in a rural area might return only a city and postal code. This is normal — the resolution depends on two factors:
Coordinate Precision
Six decimal places (e.g., 40.748817) is accurate to ~11 cm. Four decimal places (40.7488) gets you within ~11 meters. If your source data rounds aggressively, the resolved address may be approximate.
Address Database Coverage
Urban areas in the US, Europe, and major global cities have near-complete coverage down to individual buildings. Rural areas and developing regions may have less granular data. CSV2GEO covers 39+ countries with the deepest coverage in the United States.
Every result includes a confidence indicator so you can filter out low-confidence matches when precision matters. For most business use cases — fleet tracking, customer data enrichment, logistics — the results are street-level accurate.
Ways to Convert Lat Long to Address
The right tool depends on volume, budget, and whether you need a one-time conversion or ongoing lookups built into your software.
CSV2GEO File Upload
Upload a CSV or Excel file with latitude and longitude columns and download the results with full addresses appended. Purpose-built for batch coordinate-to-address conversion — handles files up to 100,000 rows with no coding, no API keys, and no per-request pricing headaches. Your first 100 lookups every day are free.
CSV2GEO Reverse Geocoding API
Integrate coordinate-to-address conversion directly into your application. Send a lat/long pair or a batch of up to 10,000 coordinates in a single request and get structured JSON responses with parsed address components. Ideal for real-time lookups in logistics platforms, mobile apps, or data pipelines. See the API documentation.
Google Maps Geocoding API
Google's reverse geocoding API returns addresses from coordinates with high accuracy in well-mapped regions. However, it requires API keys, billing setup, and costs $5.00 per 1,000 requests — ten times more than most alternatives. There is no file upload option, so every lookup requires code. Best suited for applications already embedded in the Google Cloud ecosystem.
Manual Lookup (Google Maps, OpenStreetMap)
Paste a single coordinate into Google Maps or OpenStreetMap and read the address from the pin. This works for one-off checks — verifying a single GPS point or confirming where a photo was taken. It falls apart at any volume. Ten coordinates will take you five minutes. A thousand will take you all week. There's no export, no structured output, and no way to automate it.
What You Get Back from Latitude and Longitude
CSV2GEO returns each piece of the address in its own column — ready to filter by city, group by state, or import directly into a database without parsing.
| Input Lat | Input Long | Street | City | State | Postal Code | Country |
|---|---|---|---|---|---|---|
| 40.748817 | -73.985428 | 20 W 34th St | New York | NY | 10001 | United States |
| 51.501364 | -0.141890 | Buckingham Palace Rd | London | England | SW1A 1AA | United Kingdom |
| 48.858844 | 2.294351 | 5 Avenue Anatole France | Paris | Ile-de-France | 75007 | France |
| -33.856159 | 151.215256 | 7 Macquarie St | Sydney | NSW | 2000 | Australia |
Every row also includes a combined full-address string and a confidence score. This structured output is what separates a batch reverse geocoding tool from pasting coordinates into Google Maps one at a time — clean, import-ready data instead of screenshots and copy-paste fragments.
Frequently Asked Questions
What is reverse geocoding?
Reverse geocoding converts geographic coordinates (latitude and longitude) into a human-readable street address. For example, converting 40.7128, -74.0060 into "123 Main Street, New York, NY 10001". It's the opposite of regular geocoding which converts addresses to coordinates.
What coordinate format do you accept?
CSV2GEO accepts decimal degrees format (e.g., 40.7128, -74.0060). Coordinates can be in separate columns (latitude in one, longitude in another) or combined in a single column. We auto-detect the format from your CSV or Excel file.
How accurate is reverse geocoding?
CSV2GEO provides address-level accuracy for most coordinates. Results include the nearest street address, city, state, postal code, and country. Accuracy depends on the precision of your input coordinates and address data coverage in that area.
