Convert Number to Words in SSRS

A question that is often asked is how to convert a number to words in SSRS. For example 1 => One.
Let's take a look at an example:
SELECT Sales.SalesPerson.SalesPersonID AS SalesPerson,
SUM(Sales.SalesOrderDetail.OrderQty * Sales.SalesOrderDetail.UnitPrice) AS Amount
FROM Sales.SalesOrderDetail
INNER JOIN Sales.SalesOrderHeader ON Sales.SalesOrderDetail.SalesOrderID = Sales.SalesOrderHeader.SalesOrderID
INNER JOIN Sales.SalesPerson ON Sales.SalesOrderHeader.SalesPersonID = Sales.SalesPerson.SalesPersonID
GROUP BY Sales.SalesPerson.SalesPersonID
For the sake of example, let us assume that we need to display sales person id along with the sales amount and the amount in words.
Listed below are the basic steps to create the report:
1. Create a SSRS project
2. Add new report the project
3. Add a data source in which database is pointed to adventureworks
4. Create a data set with above querys
5. Drag and drop a table to layout from the toolbox and drag and drop the fields to the table
The next step is to create a function to convert the numeric values into words.

 Go to Report menu option and select report properties. Select the Code tab in the dialog box and copy and paste the following code.

If j > -1 Then

temp2.Insert(0,suffixes(j),1)

End If

End If

temp2.Insert(0,GetNumberUnder1000Str(numPart),1)

Next

RETURN digits(Right(pNumber, 1))

Else

RETURN units(Right(pNumber, 1))

End If

End Function

The above code is adapted from said web site, but I have mad some small changes to it.
Next, you have to call this function in your table list control of the report. You need to enter the following function call at the column in which you need to have your number displayed in words.
=Code.ExpandPrice(Fields!Amount.Value,".")
The report will be dispalyed as illustrated below:
