Show Number Values as Currency

You could format string values in your JSON and populate the table with "$3.26" instead of 3.26 floats. But would require some manipulation of your data inside your flow.

You can use formatters in your template using Encodian as an alternative:

You could format the values as a string in Power Automate and insert them as string values? "$3.26"

It would require some manipulation of data in your flow. Using Encodian, you could format any values using template syntax (dates, currencies, strings, numbers, etc):

Try this out:

• Using Fields:
  • Place the cursor where you want the currency value to appear.
  • Press Ctrl+F9 to insert a field.
  • Type = and then the value or reference to the field containing the number.
  • Press Shift+F9 to toggle between the field code and its value.
  • You can add formatting codes to the field like { =1234.56 \# "$#,##0.00" }.
• Using Content Controls with Macros:
  • Insert Plain Text Content Control where you want the currency to appear, but don't type the dollar sign ($) manually.
  • Use a Macro to format these fields. Here is a sample VBA code that formats content controls as currency:

Sub FormatCurrency()
    For Each cc In ActiveDocument.ContentControls
        If cc.Type = wdContentControlText Then
            If IsNumeric(cc.Range.Text) Then
                cc.Range.Text = Format(cc.Range.Text, "$#,##0.00")
            End If
        End If
    Next cc
End Sub

• Using Quick Parts:
  • Go to Insert -> Quick Parts -> Field.
  • Select Field Codes... and type in the currency formatting you need.
  • Save the Quick Part for future use.
