# Data Preparation

Data preparation is the process of collecting, cleaning, and transforming raw data into a format that can be easily analyzed and used for various applications.

Data Preparation involves gathering, refining, and converting raw data is a critical step in data analysis and machine learning, as the quality and accuracy of the data used directly impact the accuracy and reliability of the results. The data preparation is to ensure that the data is accurate, complete, consistent, and relevant to the analysis. By using this action, the data scientist can make more informed decisions, extract valuable insights, and unveil concealed trends and patterns within the raw data.

* The ***Data Preparation*** page opens displaying the dataset in the grid format.
* Apply the required transforms on the data set. E.g., There is an empty column in this dataset. The user can either select the ***Delete*** column option from the column context menu or choose it from the ***Transforms*** tab.
* Provide a name for the Data Preparation.
