![]() ![]() □ Learn More: I have compiled an “ultimate guide” on the Finxter blog that shows you the best method, respectively, to convert a CSV file to JSON, Excel, dictionary, Parquet, list, list of lists, list of tuples, text file, DataFrame, XML, NumPy array, and list of dictionaries. The first row of the CSV is used as a header to determine the keys of the dictionary that are mapped to the values defined in the individual rows of the CSV file: More Python CSV Conversions The result of the previous code snippet is a list of dictionaries. Here’s the code to convert that CSV file to a list of dictionaries, one dictionary per row by using the csv.DictReader(file) function: import csvĪ dictionary is a data structure that maps keys to values. If you visualize this CSV in table form, it looks like this: Name Here’s the content of an example CSV file "my_file.csv" used in our code snippet below: Name,Job,Age,Income Let’s have a look at a simple example to demonstrate this solution next! Basic Solution: CSV to List of Dicts – Example As the last step, convert the iterable of dictionaries to a list using the Python built-in list() function.Each dictionary maps the column header from the first row to the specific row value. The return value is an iterable of dictionaries, one per row in the CSV file.Create a CSV file object f using open("my_file.csv") and pass it in the csv.DictReader(f) method.Save my name, email, and website in this browser for the next time I comment.Convert a CSV file to a list of Python dictionaries in three steps: ![]() Your email address will not be published. That’s all about how to convert CSV to dictionary in Python. We can also use the csv.reader class for this, but we have to perform some complex operations to convert this data to a dictionary and append them to a list. The csv.DictReader can parse the csv to dictionaries which can be appended to a list. ![]() The same pandas.to_dict() method can be used for this but we specify the format of the final dictionary as records. We also discussed how to convert CSV to list of dictionaries. We also used the numpy.loadtxt() method for the same. The pandas module provides a direct method to read CSV and convert it into a dictionary with the to_dict() function. We could also use the filter() function with this method. ![]() The csv module was used to parse the CSV data and convert it to a dictionary. We discussed the basic structure of both these objects and how the final format may be different in different ways. We discussed different methods to convert CSV to dictionary in Python.
