Features of Tableau Prep Builder

Connect and extract data

More than 40 data sources are available to connect to and extract data.
Also, you can connect to other JDBC and ODBC drivers with valid credentials.
In addition, you can use the Tableau Server’s previously released data to build a flow.

Clean the Data

Cleaning is the crucial phase that enables you to clean up the data following your requirements.
For example, the data can be cleaned using Filter, Group values, and Replace values with Null values.
Tableau Prep also has the choice to do Cleaning operations through smart recommendations.

Group and Replace

The presence of multiple values instead of a single is a frequent problem while cleaning data (such as UK and United Kingdom).
Tableau Prep Builder’s group and replace function address this problem in the cleaning step.
Using this function, you can group similar categories based on certain criteria. You can either manually select or use Pronunciation, Common Characters, and Spelling options to group values.

Join and Union

You can easily combine multiple data sources with Join and Union functions from the Tableau Prep Builder.
Join is the merging of data based on common fields. When two tables are combined using the Join function, the final result displays the data from the first table’s columns alongside the second table’s columns in the same row. Review the Join results through Summary in the Join profile, which displays metadata about the join.

Union is combining data into new rows. When two tables with the same number of fields, field names, and data type are Unioned, the final table shows the data from the first and second tables in the same table.

Pivoting Data

Pivoting columns to rows or vice versa when evaluating data in a crosstab style is challenging. Tableau Prep Builder makes pivoting visual, so you can see how your data changes at each stage.
You can use options to pivot columns to rows or vice versa. Or use wildcard search to pivot fields based on a pattern match.

Filtering

Filtering assists in excluding unwanted entries from your data or limits the range while preparing for analysis
Tableau Prep Builder has rich filter options to filter spectra of numbers or dates. Click a drop-down arrow in the profile pane to add a filter.
Additionally, you can keep or delete entire fields.

Aggregation

In the Aggregate step, you modify the level of detail, i.e., the Granularity of the data, to make it easier to join or union with other data sets.
It is useful when you want to match with other data structures.
Some aggregate options for numerical fields are Sum, Average, and Median. For non-numerical fields, the options include Count and Count Distinct.
For example, an online product-based company wants data to optimize its consumers’ digital experiences through personalized messages. You can aggregate the data on customer demographics and then join it with the behavior indicators (like no.of purchases and subscriptions) to acquire the desired data.

Conclusion

Instead of writing a ton of code, you can instantly transform your data with Tableau Prep Builder. The interface is a delight to work with, and once you get used to it, Tableau Prep Builder is a spectacle for cleaning and organizing data.
