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.
    - New operation
      Add or insert a new operation to your analysis in the timeline.
    - Operation controls
      The operation controls allow you to make changes to any operation in your data analysis at any point in the timeline.
    - Submit controls
      The submit controls allow you to submit or cancel changes made to an operation.
    - Expression Editor
      Use the Expression Editor to build valid selection and value expressions in the Trillion-Row Spreadsheet.
    - Filter a list of columns
      Limit the number of column biscuits that are displayed in an operation panel section.
  - 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.
  - 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.

Expression Editor

Use the Expression Editor to build valid selection and value expressions in the Trillion-Row Spreadsheet.

The Expression Editor assists in composing 1010data Insights Platform expressions when selecting rows or creating computed columns in the Trillion-Row Spreadsheet (TRS).

The Expression Editor is available in the following locations of the TRS:

Expression Editor view of the Select rows panel
Computed column panel
Amend column panel
Find rows dialog in the grid

In the images below, a partial sample expression is entered in the Expression Editor for illustrative purposes.

The Expression Editor helps you build valid 1010data Insights Platform expressions within the TRS by providing:

Suggestion of columns, variables, and functions. Suggestions include descriptions of all system variables. Use the Up Arrow and Down Arrow keys or the mouse to navigate the list of suggestions. Press the Tab key or click the menu item to insert it.
An inline function reference. While editing the subexpressions representing any function's arguments, the top portion of the context menu indicates the argument index and a description of that argument's constraints and purpose.
Detection and highlighting of mismatched delimiters (e.g., brackets, braces, quotation marks, and parentheses).
Highlighting of the current enclosing delimiters.
Suggestion of closing delimiters and the implied semicolon separators for function calls. To accept the suggestions, press the Right Arrow key.
Coloring of quotations, so they stand out easily.
Context-aware insertion and replacement. If the cursor is positioned within an existing column, variable, or function, choosing a replacement from the context menu replaces the item with the new selection.
Convenient text selection. To select text from the location of the cursor to the beginning of the entry field, press Ctrl+Shift+Left Arrow. To select text from the location of the cursor to the end of the entry field press Ctrl+Shift+Right Arrow.
