Read all json files in directory python
One option is listing all files in a directory with os.listdir and then finding only those that end in '.json': Show
Now you can use pandas DataFrame.from_dict to read in the json (a python dictionary at this point) to a pandas dataframe:
Prints:
In this case I had appended some jsons to a list The following code sums up everything above:
for me this prints:
It may be helpful to know that for this code I had two geojsons in a directory name 'json'. Each json had the following structure: Comparing data from multiple JSON files can get unweildy – unless you leverage Python to give you the data you need. I often monitor key page speed metrics by testing web pages using WebPagetest or Google Lighthouse using their CLI or Node tools. I save test results as JSON, which is fine for looking at individual snapshots at a later time. But I often end up with folders full of data that cannot really be analyzed manually:
For example, how to compare changes in those metrics over time? Or how to look for a peak in the data? The following handy little Python 3 script is useful for sifting through a directory full of JSON files and exporting specific values to a CSV for an ad-hoc analysis. It only uses built-in Python modules. I just drop it in my working directory and run it via command line with json-to-csv-exporter.py
That gives you a CSV that you can use to create charts or analyze to your heart’s content.
