They enhance effectiveness, thickness, and reusability in data querying and analysis processes.

Data Preview
It allows druggies to see a sample of the data before applying any metamorphoses, furnishing a quick overview of the dataset's structure and contents. The Data Preview section displays the first many rows of the imported data, along with the column heads, enabling druggies to assess the quality and felicity of the data for farther analysis or manipulation.
