![]() **Note: **I recently learned that pandas.io.json.json_normalize is deprecated. # uncomment below if installation needed (not necessary in Colab) Step 0 - Import Libraries # to handle data retrieval The result is a Pandas DataFrame that is human readable and ready for analysis. Second, use Pandas to decode and read the data. I am running this project in Google Colab and you can skip right to the notebook below or following along the steps in this story.Īlthough I break down the project into several steps, it is really two-part.įirst, start with a known data source (the URL of the JSON API) and get the data with urllib3. Also, I think this method lends itself better to automation as part of a workflow or data pipeline.īasic Task - Read data from the OpenData API URL directly into a Pandas DataFrame in Python. However, while the spreadsheet download and ingest method works just fine, we can perform the “get” task in just one step by reading data directly into a Pandas DataFrame. To be sure, we can easily download data in CSV or Excel formats and then process that data to whatever end. Once I get the data, I can run statistics, create visualizations, and hopefully, learn something worth sharing. and want to leverage the city’s OpenData portal to further my research. In this project, I’m researching crime in Washington, D.C. To understand more on the technical background of JSON, check out this article on. ![]() In addition, my solution accounts for a Pandas update to json_normalize as well as handling certificate validation warnings when getting data over the Internet. ![]() The topic of JSON in Python with Pandas is a well-worn path however, in this story, I share a straight-forward solution that handles the task of getting JSON data from an API into your Pandas DataFrame. As a result, chances are high that you will eventually have to tackle the JSON to Pandas problem in Python. On the flip side, Python and Pandas have become the go-to tools to help us analyze and visualize data. However, while JSON is well suited to exchange large amounts of data between machines, it’s not easy for humans to read or process. There is a ton of data out there on the web and much of it exists in a specific format called JavaScript Object Notation (JSON).
