ErrorThis Snap has at most one document error view and produces zero or more documents in the view. Each document contains input data that has caused an error while processing.



Required. The name for the Snap. You can modify this to be more specific, especially if you have more than one of the same Snap in your pipeline.

Sheet name

The name of the Excel sheet.

Example: Members
Default value: {[None]

Write header

Required. This option specifies whether or not the Snap should write the header to the output.
Default value: Selected

Ignore empty stream

If the property is unchecked, an empty array will be written to the output view in case no documents were received on the input view. If the property is checked, then the Snap will write nothing to the output view in case no documents were received on the input view.

Default value: Not selected

Convert numeric string to number

This property sets the behavior of the Snap when a value in the input document is a numeric string.

If selected, the Snap converts the value to a numeric-type cell.

If not selected, the Snap sets the value to a string-type cell.

Default value: Selected

Translate date and time types

This property sets the behavior of the Snap when a value in the input document is a date and/or datetime type.

If selected, the Snap does not convert the date and/or datetime types to text/string and instead converts it to Excel date numeric type with date format style.

Default value: Not selected

Include all columns

The Snap uses the first input document to write the header. If subsequent input documents have additional fields, truncate rows or columns in between, they are not included in the output. 

If this property is selected, the Snap detects those additional fields in all the input documents, updates the header and includes all values in the output.

If not selected, and the subsequent input document has any truncate values, an empty output data preview is displayed.

Writing to Multiple Excel Sheets in the Output

This example demonstrates how you can use the Excel Formatter Snap to classify Excel data and route it to different worksheets in the output file based on the values in a specific field.

Download the Pipeline.

In the sample Pipeline, the JSON Generator Snap output contains records with two values for the country field, Canada and United States

In the Excel Formatter Snap, if you select the value $country in the Sheet name field, the input data is organized into two sheets based on each unique value in the country field.

The Snap's output preview shows records for Canada grouped together in one sheet:

The final output shows an Excel file containing two worksheets, one for Canada and the other for United States.

Similarly, you can select any field in the Sheet name drop-down list to create an output file with separate sheets for each unique value of the field.
