# Sheet Configuration Guides

> These guides cover all aspects of configuring Nextedy POWERSHEET sheet configurations -- from adding columns and defining views to applying styles, formatters, and data sources.

export const LastReviewed = ({date}) => {
  if (!date) return null;
  const formatted = new Date(`${date}T00:00:00Z`).toLocaleDateString("en-US", {
    year: "numeric",
    month: "long",
    day: "numeric",
    timeZone: "UTC"
  });
  return <p className="mt-10 text-sm text-gray-400 dark:text-zinc-500 not-prose">
      Last reviewed on {formatted}
    </p>;
};

## Column Setup

**[Add a Column](/powersheet/guides/sheet-configuration/add-column)** -- Define columns in your sheet configuration using binding paths to entity properties

**[Configure a Column Group](/powersheet/guides/sheet-configuration/configure-column-group)** -- Organize related columns under collapsible group headers with shared styling

**[Configure Collapsible Groups](/powersheet/guides/sheet-configuration/configure-collapsible-groups)** -- Enable collapse/expand behavior for column groups

**[Add External Reference Column](/powersheet/guides/sheet-configuration/add-external-reference-column)** -- Display external reference work items linked through relationships

**[Configure Multi-Item Column](/powersheet/guides/sheet-configuration/configure-multi-item-column)** -- Show and edit one-to-many or many-to-many relationships in a single column

**[Configure Read-Only Column](/powersheet/guides/sheet-configuration/configure-read-only-column)** -- Prevent user editing on specific columns

## Display and Formatting

**[Apply Column Styles](/powersheet/guides/sheet-configuration/apply-style)** -- Use predefined or custom styles for column headers and cells

**[Configure a Formatter](/powersheet/guides/sheet-configuration/configure-formatter)** -- Apply conditional formatting rules with expressions and styles

**[Use JavaScript Display Functions](/powersheet/guides/sheet-configuration/use-javascript-display)** -- Render custom HTML in cells using JavaScript arrow functions

## Views and Layout

**[Create a View](/powersheet/guides/sheet-configuration/create-view)** -- Define named column visibility presets for switching between different analysis perspectives

## Data Sources and Assignment

**[Configure Sources](/powersheet/guides/sheet-configuration/configure-sources)** -- Define data sources, queries, and expansion paths for loading entity hierarchies

**[Assign Configuration to Document](/powersheet/guides/sheet-configuration/assign-config-to-document)** -- Link a sheet configuration to a Polarion LiveDoc

**[Download Configuration as YAML](/powersheet/guides/sheet-configuration/download-config-as-yaml)** -- Export your current sheet configuration for backup or sharing

<Tip title="Start with a minimal configuration">
  Begin with a single entity type, a few columns, and one data source. Extend incrementally -- adding column groups, formatters, and views once the basics are working. See [Incremental Configuration Approach](/powersheet/getting-started/incremental-configuration) for guidance.
