The Collier County Property Appraiser provides public data in downloadable ZIP file format. These files are updated regularly and contain property, sales, building, land, legal, and other records that can be used for reporting and analysis. Each file contains a CSV (Excel-compatible) version of the data.
Most files can be linked together using the PARCELID field. This allows you to join sales
records to parcel data or connect land and building data to their corresponding parcels. Tangible
Personal Property (TPP) accounts use a separate ACCOUNTID for tracking, but
also include a PARCELID so the personal property can be associated with a real estate
parcel when applicable - for example, showing which unit a business occupies in a shopping center.
The files correspond to our internal database tables. Here's a summary of what's available:
PARCELID).ACCOUNTID, PARCELID).PARCELID).PARCELID).PARCELID).PARCELID).SUBCONDO).MILLAGEAREA).USECODE values (e.g., residential, commercial).BLDGCLASS values from the Buildings file.NAICSCODE).PARCELID, TAXYEAR).ACCOUNTID, TAXYEAR).Note: Permit data is not included because it is maintained by external permitting agencies, not the Property Appraiser's Office.
Go to the Data Downloads section from the menu on the left side of our homepage. Files are grouped under sections like "Tax Roll / CAMA Database Exports" or "Lists, Data & Codes."
Click on the file you want (e.g., Parcels, Sales, Building), and your browser will download a ZIP file containing a CSV file (or occasionally multiple CSVs).
After downloading, right-click each ZIP file and choose Extract All.... Save the contents to a single folder for easier access later.
You can open the CSV file using Microsoft Excel in one of two ways:
Tip: If Excel shows a message about converting data and removing leading zeros, click Convert to proceed. You can reformat the affected columns after opening if needed.
Why format as a table?
Formatting your data as a table in Excel makes it easier to filter, sort, and analyze large datasets. It also improves visibility and helps when using formulas like VLOOKUP or XLOOKUP.
How to create and format tables

Once your data is formatted as a table, Excel adds drop-down arrows at the top of each column. These allow you to filter and sort your data quickly without changing the file's structure.

Why join files?
Each downloadable file represents a different aspect of property
data. Linking them using PARCELID (or ACCOUNTID for TPP) allows you to build a
more complete picture of each property or perform detailed analysis.
The Parcels file is the central file and can be linked to these supporting datasets:
You can link in either direction depending on your goal. For example:

How to link files in Excel using VLOOKUP:
VLOOKUP formula to match PARCELID or ACCOUNTIDExample using VLOOKUP:
=VLOOKUP(A2, 'Sales.csv'!A:C, 3, FALSE)
This finds the value in column 3 of the Sales file where the PARCELID in cell A2 matches a
row in column A of the Sales file. Adjust ranges and columns as needed.

Many fields in the data files use numeric or abbreviated codes to represent property use, building types, subdivisions, and business categories. To make this data more readable, you can join these fields with the corresponding lookup tables found under Lists, Data & Codes on the downloads page.
Available lookup files include:
USECODE field (e.g., residential,
commercial)BLDGCLASS values from the Buildings fileSUBCONDO field
MILLAGEAREA. The
millage area defines the tax rate district a parcel falls into.NAICSCODE values for Tangible Personal Property
accountsHow to apply code descriptions in Excel using VLOOKUP:
VLOOKUP to match the code in the main file to the description in the lookup file
Example: Add a Use Code description to the Parcels file:
=VLOOKUP(B2, 'UseCodes.csv'!A:B, 2, FALSE)
This formula looks up the USECODE in cell B2, finds it in column A of the Use Codes file,
and returns the description from column B.
