How to Use Janitor AI

Janitor AI is a powerful tool that helps automate data cleaning and processing tasks. In this post, we will explore how to leverage Janitor AI’s capabilities and streamline your data management workflow.

Step 1: Installing Janitor AI

To begin, you need to install Janitor AI on your preferred programming language environment, such as Python or R. You can do this by executing the following command in your terminal:

pip install janitor-ai

Step 2: Importing Janitor AI

Once installed, you can import Janitor AI in your Python or R script using the following code:

python
import janitor_ai as jai

Step 3: Cleaning Data

Now that you have Janitor AI imported, you can start cleaning your data. Janitor AI provides various functions for common data cleaning tasks, such as removing duplicates, handling missing values, and correcting data types.

For example, to remove duplicates from a dataframe in Python, you can use the clean_duplicates() function:

“`python
import pandas as pd

Assuming ‘df’ is your dataframe

cleaned_df = jai.clean_duplicates(df)
“`

Similarly, in R, you can use the clean_duplicates() function from Janitor AI:

“`R

Assuming ‘df’ is your dataframe

cleaned_df <- clean_duplicates(df)
“`

Janitor AI offers many more data cleaning functions that you can explore in the official documentation.

Step 4: Enhancing Data Quality

Janitor AI also provides functionality to enhance data quality by performing operations like renaming columns, setting data types, and standardizing formats.

For instance, to rename columns in a dataframe, you can use the rename_columns() function in Python:

“`python

Assuming ‘df’ is your dataframe

new_df = jai.rename_columns(df, {‘old_column’: ‘new_column’})
“`

In R, the rename_columns() function can be used as follows:

“`R

Assuming ‘df’ is your dataframe

new_df <- rename_columns(df, c(‘old_column’ = ‘new_column’))
“`

Step 5: Automating Data Processing

To streamline your data processing workflow further, Janitor AI allows you to create pipelines by combining multiple data cleaning and enhancement operations.

Here’s an example of how you can create a pipeline in Python:

“`python
pipeline = jai.Pipeline()
pipeline.add_step(jai.clean_duplicates)
pipeline.add_step(jai.rename_columns, {‘old_column’: ‘new_column’})

Assuming ‘df’ is your dataframe

processed_df = pipeline.run(df)
“`

Likewise, in R, you can create a similar pipeline:

“`R
pipeline <- Pipeline()
pipeline$add_step(clean_duplicates)
pipeline$add_step(rename_columns, c(‘old_column’ = ‘new_column’))

Assuming ‘df’ is your dataframe

processed_df <- pipeline$run(df)
“`

Conclusion

In this post, we have learned how to use Janitor AI to automate data cleaning and processing tasks. By adopting Janitor AI into your workflow, you can save time and effort while ensuring data quality. Experiment with the various functions and pipelines provided by Janitor AI to suit your data management needs. Happy cleaning!
