Template Syntax

Placeholders

Use double curly braces:

{{ PropertyName }}

Examples:

• {{ Name }}
• {{ Amount:N2 }}
• {{ Customer.BankingDetail.BankName }}

Nested Paths

Dot notation is supported:

{{ Customer.CompanyName }}
{{ Customer.BankingDetail.AccountNumber }}

If any intermediate nested object is null, output is empty for that placeholder.

Loops

{{ #foreach(Items) }}
  {{ Name }} x {{ Quantity }}
{{ #endforeach }}

Looping primitive arrays

Use . for the current item:

{{ #foreach(Tags) }}[{{ . }}]{{ #endforeach }}
{{ #foreach(Tags) }}[{{ .:uppercase }}]{{ #endforeach }}

Conditions

{{ #if(Age >= 18) }}Adult{{ #else }}Minor{{ #endif }}

Supported operators:

• ==
• !=
• >
• >=
• <
• <=

Conditions work with numbers, strings, booleans, dates, and collection counts.

Formatting

Standard .NET style formats

• Number: N2, #,##0
• DateTime: yyyy-MM-dd, dd-MMM-yyyy hh:mm tt

Examples:

• {{ Price:N2 }}
• {{ Price:#,##0 }}
• {{ PaymentDate:yyyy-MM-dd }}

Built-in string transforms

Format	Description
uppercase	Uppercase value
lowercase	Lowercase value
titlecase	Title case value
length	Character count
ToMD5	MD5 hash
ToBase64	Base64 encode
FromBase64	Base64 decode

Examples:

• {{ Name:uppercase }}
• {{ Value:ToBase64 }}

Unknown Placeholder Behavior

Regular placeholders with unknown property names remain unresolved:

{{ UnknownProperty }}
