Pandas read csv with extra commas in column

Pandas read csv with extra commas in column

If you have extra commas within a column in a CSV file and you want to read it into a pandas DataFrame without issues, you can handle this situation by specifying the appropriate options using the read_csv() function.

Here are a couple of approaches you can use:

  1. Quote the Column with Commas: If the column containing extra commas is enclosed in double quotes, you can use the quotechar parameter to specify the quote character used in the CSV file.

    import pandas as pd # Read CSV with extra commas, quoting the problematic column df = pd.read_csv('your_file.csv', quotechar='"') print(df)

  2. Custom Separator: If the extra commas are causing issues, you can specify a custom separator character that doesn't conflict with the commas in the column.

    import pandas as pd # Read CSV with custom separator df = pd.read_csv('your_file.csv', sep='|') # Use a separator that's not present in the data print(df)

  3. Use Regular Expression for Separator: If your data uses a consistent pattern that you can use as a separator, you can use a regular expression as the separator to handle the extra commas.

    import pandas as pd # Read CSV with regex separator to handle extra commas df = pd.read_csv('your_file.csv', sep='[,]+', engine='python') print(df)

You'll need to adjust the options based on the structure of your CSV file. The examples provided above assume that you are dealing with CSV files with extra commas within a specific column.
