Select Values in the Data Grid

When you select values in the data grid, the Selection Details panel presents a set of suggestions for your review. See below.

Suggestions

Suggestion cards provide a means to select relevant suggestions for transform steps. The suggestions vary depending on the data you have selected. You can then use the cards to preview the results in the data grid, so that you are confident that the proposed transformation works for your dataset.

In the following example, your dataset contains a column of addresses. Within one of the values, you can select a zip code, which then triggers an appropriate set of suggestion cards:

Suggestion Cards

In the above image, the first suggestion in the Extract values matching suggestion card has been selected by default, and its parameters have been specified to extract all zip codes from the source column (Address). While useful, this selection may not be your intention. Options:

1. Hover over different suggestions. A mini-preview appears to the left of the suggestion.

2. Click a different suggestion in the same card. In this case, you might click the first suggestion in the Replace card, so that you can remove zip code.

   Tip: Optionally, suggestions can be provided to you based on your prior transformations or the transformations of other users in your workspace. These suggestions appear under the Recently used heading. For more information on enabling collaborative suggestions, see Workspace Settings Page.

   Tip: Among the suggestion cards, scroll down to see other suggestion cards that are off-screen. If it is present, a See all link displays more suggestions in that card. Variants further down in the suggestion card typically become more specific in their changes to the dataset or rarer in their usage.

3. Modify the selected transform. To edit the step, click Edit. You can fine-tune parameters of the transformation. See Transform Builder.
