# The Calc ribbon

> A reference for every group and button on the Calc tab, and when each appears.

Everything in Calc runs from the **Calc tab** on the Excel ribbon. The tab is
context-aware: groups appear and disappear depending on whether you are signed
in, and whether the open template is in **Use** or **Design** mode.

## Always available

| Button | What it does |
| --- | --- |
| **Log in** / **Log out** | Sign in to or out of your GIMLabs account. |
| **About** | Version and application information. |

## After you sign in

| Group | Button | What it does |
| --- | --- | --- |
| Project | **Projects** | Pick the project to work on. |
| Templates | **Templates** | Browse the project's templates and open, edit, create or import one. |
| Selected | *(labels)* | Shows the current **Project**, **Configuration** and **Template**. |
| Mode | *(label)* | Shows whether you are in **Use** or **Design** mode. |

You pick a **project** first; **Templates** and the **Selected** and **Mode**
labels then fill in as you choose a project and open a template. Opening a
template puts you into one of the two modes, which changes the rest of the
ribbon.

## Use mode (collecting data)

When you open a template to collect data:

| Group | Button | What it does |
| --- | --- | --- |
| Data | **Collect** | Pull the project's data into the workbook, applying filters and charts. |
| Data | **Clear** | Remove the sheets a Collect created and return to the template. |

See [Collecting data](/calc/collecting-data) for the full workflow.

## Design mode (building templates)

When you open a template to edit it:

| Group | Button | What it does |
| --- | --- | --- |
| Build | **Tables** | Choose a table's columns, filters, sorting, grouping and start cell. |
| Build | **Charts** | Map each chart's series to data columns. |
| Build | **Constants** | Stamp project values (Project Name, Client, ...) onto the template. |
| Macros | **Macros** | Choose which workbook macros run automatically after Collect. |
| Sheets | **Sheets** | Choose which worksheets are kept when the template is saved. |
| Save | **Save** / **Save As** | Save changes back to the template, or save a copy as a new one. |

See [Building templates](/calc/building-templates) for the full workflow.

<Callout type="note" title="Why some buttons are hidden">
  The ribbon only shows what applies to you. The **Design mode** tools (Build,
  Macros, Sheets, Save) need a role that allows creating or editing templates -
  and they are unavailable on the **Go** tier entirely, where Calc is
  **collect-only**. So a missing button is almost always down to your mode, role
  or plan. See [Core concepts](/calc/concepts#modes-and-permissions).
