# Select Header

> Settings for the step where users pick the row that holds their column headers, including how to set the default header row.

Select Header is the second tab under **Sheet Settings** → **Import Steps**. On this step, users confirm which row of their file holds the column headers.

After a user adds a file, they select the row that contains the column headers before the importer moves on to [Map Columns](/sheet-settings/import-steps/map-columns). The import flow runs in this order: upload, select the header row, map columns, then [Verify Data](/sheet-settings/import-steps/verify-data).

## Skip this step

Hide the **Select header row** page from users.

## Help text

Add help text to the header selection page, separately for each language. The help text supports Markdown formatting for bold, italics, and links.

## Default row selection

Choose which row is pre-selected on the header selection step. If you leave it empty, the first row is selected.

If your users' files usually have a title or blank rows above the headers, set the `default_header_row` option so the right row is already selected on the **Header Selection** page. Rows are 1-indexed.

```javascript theme={null}
importer.setOptions({
    default_header_row: 3
})
```

Also available as an installation parameter: [`default_header_row`](/getting-started/2-install-code#default_header_row). See [Options](/getting-started/2-install-code#default_header_row) on the Install the Code page for how to pass this option in each framework.

## Show encoding option

Show or hide the character set selection list to users. UTF-8 is the default.

## Show switch row/columns option

Show or hide the option that lets users switch rows and columns.

<Tip>
  Hiding the options you don't need removes non-essential choices from the importer and makes the experience cleaner for your users.
</Tip>

## Files with complicated headers

If uploaded files have headers the importer can't use as they are, such as two-row merged headers, [AI Pre-Import Transform](/dashboard-settings/ai-pre-import-transform) can restructure the file before it reaches column mapping.

## Track drop-offs

[Import Analytics](/dashboard-settings/import-analytics) shows how many users reach and complete header selection, and how long they spend on it.
