Customizing content using a Microsoft Excel template

When configuring a Send an email, Call a webhook, or Create a new file task, customize content using a Microsoft Excel template by performing one of the following tasks:

For information about customizing the template, see Customizing content using templates and the tips provided below.

Viewing the template

After creating or selecting the template, click View adjacent to the template property to view the template.

Note: We do not recommend that you edit the template in this view due to the built-in limitations in the way Microsoft Excel files can be opened and edited from the web.

Editing the template

To edit the template, open the Microsoft Excel template from your data source.

Building the Microsoft Excel template

AppSheet supports only simple Microsoft Excel templates.

The first row in the Excel template can contain only column header values.

The second row in the Excel template can contain only a Start expression, one or more cell data values, and an End expression, as follows:

  • The left-most cell contains a Start expression immediately followed by a data value or Microsoft Excel worksheet formula.

  • Intermediate cells contain data values or Microsoft Excel worksheet formulas.

  • The rightmost cell contains a data value or Microsoft Excel worksheet formula immediately followed by an End expression.

The Start expression retrieves a set of rows from a table you specify. Each retrieved table row populates a row in the resulting Excel file.

In the following example, the Start expression retrieves rows from the Customer table. The resulting Excel file contains one row for each customer who is 21 years of age or older.

Using Excel worksheet formulas

Your template can include Excel worksheet formulas. In the following template, the Total column contains a worksheet formula which multiplies Price and Qty.


Formatting cells

You can apply Excel formatting to the cells of the template. For example, the Price cell could be formatted as a Currency value.

Using multi-worksheet workbooks

Your Excel workbook template can contain one or more worksheets each of which is a template. The resulting .xlsx file contains each of these worksheets.


  1. Excel tables are not supported. Templates must be simple worksheets.

  2. Excel pivot tables are not supported.

  3. Nested tables cannot be displayed in the same Excel worksheet. For example, you cannot display each Order record followed its child Order Detail records.


You may see the following Excel error message when you attempt to open the resulting Excel .xlsx file.

Excel cannot open the file <filename>.xlsx because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file.

This error can occur if you use a Google Docs template file rather than a Microsoft Excel template file. If you inadvertently use a Google Docs template file, the output is an HTML file that may look like an Excel worksheet but it will not be a valid Excel .xlsx file.
