Trillion-Row Spreadsheet
The Trillion-Row Spreadsheet (TRS) allows you to visually interact with your data.
- Analyze
  The Analyze tab displays the object browser and the Analysis Timeline.
  - Object browser
    The object browser provides a hierarchy of folders and objects to which you have access. Use the object browser to select the base table or query for your analysis.
  - Analysis Timeline
    The Analysis Timeline displays a visual representation of your data analysis in the Trillion-Row Spreadsheet.
  - Selecting rows
    Selecting rows is one of the most basic tasks in the 1010data Insights Platform. Use row selection to isolate data that is important to your analysis and create more efficient queries.
  - Sorting rows
    You may reorder the rows of a table such that the values in a particular column are in ascending or descending order.
  - Arranging columns
    You can display a subset of the columns in a table and specify the order in which they appear.
  - Linking tables and worksheets
    Use linking to combine tables or worksheets into a single, bigger table with columns from both.
  - Computed column
    A computed column is a column that you add to a table, whose values are typically based on one or more existing columns.
  - Summarizations and tabulations
    Some of the basic ways to analyze your data include quick summaries, tabulations, and cross tabulations.
  - Merging tables and worksheets
    You can merge two or more tables or worksheets to combine their rows together into a single, larger worksheet.
  - Amending values
    Replace the values in a table or worksheet using the amend operation.
    - Amend column panel
      The Amend column panel allows you to choose a column and enter a value expression to replace values in a table or worksheet.
    - Amend values in a column using an expression
      Recompute the value of a column or specific rows of a column by using a value expression.
    - Amend a single value within the grid
      Change the value of a cell directly from within the grid.
      - Amend values panel
        The Amend values panel appears in the Analysis Timeline after a single value is amended within the Grid view of the Trillion-Row Spreadsheet.
  - Running custom code
    You can run custom SQL, Python, R, or K3 code within the TRS Analysis Timeline.
  - Miscellaneous operations
    In addition to the five basic operations, you can choose to use a miscellaneous operation in the Trillion-Row Spreadsheet.
- Query
  The Query tab displays the current timeline query as Macro Language XML code. It also provides the ability to undo and redo operations in the timeline.
- View
  Select among the ways to view and interact with the data resulting from your analysis.
- Visualize
  The 1010data Insights Platform provides a mechanism to generate high-quality charts, which in turn can support the notion of visual data discovery.
- Develop
  Use the query that represents your analysis as a base for further development.
- Export
  Export the data resulting from your analysis to various destinations.
- Results pane
  The results pane is displayed on the right side of the Trillion-Row Spreadsheet window and Macro Language Workshop.

Amend a single value within the grid

Change the value of a cell directly from within the grid.

You can quickly edit the value of a cell in a table or worksheet directly from within the grid in the Trillion-Row Spreadsheet. This allows you to easily update data without needing to write an expression.

To amend a single value within the grid:

In the Grid view of an open table or worksheet, double-click the cell containing the value you want to amend.
The Trillion-Row Spreadsheet changes the cell to an editable field.
Make the desired changes to the value and then do one of the following:
- Press Enter (PC).
- Press Return (Mac).
- Click anywhere outside of the field.
The Trillion-Row Spreadsheet updates the cell value in the grid and adds the Amend values panel to the Analysis Timeline.

The Amend values panel displays information about the value amended in the grid. Specifically, the panel lists the row and column of the amended cell and the new value. For more information, see Amend values panel.
