Data Grid
The data grid is the primary display, with a spreadsheet-like cell-by-cell view. It’s intended to scale efficiently to relatively large in-memory datasets, up to millions of rows or columns.
Each column header has the column name above the data type, which is dependent on the backend type (language runtime or DuckDB). At the top right of each column, there is a context menu to control sorting or to add a filter for the selected column. Resize columns by clicking and dragging the column’s borders.
Row labels default to the observed row index, with a zero-based index in Python and a one-based index in R. Alternatively, pandas and R users may also have rows with modified indices or string-based labels.
For long strings or other data values that do not fully fit in a grid cell, you can see a tooltip containing the complete value by hovering over the cell:
If the column is labelled, the tooltip will include the label.
Each Data Explorer instance watches the underlying data for changes, so if you edit a data file or modify an in-memory dataframe, the changes will be reflected in the Data Explorer.
Supported data frame libraries
pandas and Polars DataFrame objects are supported in Python, and data.frame, tibble, and data.table are supported in R. Previews of database connections managed by the Connections Pane are also supported, for both Python and R.
Based on user feedback, we may add support for other libraries that expose a tabular data interface.
Sorting
To sort the data by a column’s values, open a column’s context menu from the top of the grid and click either “Sort Ascending” or “Sort Descending”:
To clear an individual column’s sort, click on the column header and select “Clear Sorting” from the context menu.
When a column is sorted, the column header will have an arrow pointing up or down indicating the sort direction. You can sort by multiple columns by opening the context menu for a second column and sorting it, too. The number next to the sort direction indicates the sort order of the column.
A Data Explorer can be sorted and filtered at the same time without any issues.
To clear all sorting, click on the “Clear Column Sorting” button in the top action bar:
Grid selection and copy-and-paste
The data grid has copy-and-paste capabilities similar to a spreadsheet. You can select:
- A single cell
- A rectangular range of cells
- One or more entire rows
- One or more entire columns
To copy a single value, click on the cell of interest and press . You can also copy using the right-click context menu:
To copy a rectangular range of cells, first click on a cell, then hold the ShiftShift key and click on another cell to select the range of interest. Then either press or use the context menu to copy:
When you copy a rectangular range of cells, the values are copied along with the column names in tab-separated format to ease pasting into Excel or Google Sheets.
To copy whole rows or columns, click on the first row label or column label then either hold ShiftShift and click on another row or column label to select a range, or use to select individual rows or columns, but not necessarily a range:
Like copying a rectangular range of cells, copying an entire row or column will include the column names in the tab-separated output.
