Printing Text

Printing text is one of the most basic operations when building a document in Eledo.

A Text Box allows you to insert dynamic values into your document — such as names, prices, dates, or calculated values.

Instead of writing static text, you define what value should appear when the document is generated.

How it works​

Each Text Box is connected to a value using the Data (expression) field.

This field can either:

  • reference a simple input value
  • or evaluate an expression to transform data during document generation

This value is then filled in when generating the document through integrations (Make, Zapier, API, etc.).

Basic example​

Using a simple field:

Name

prints the value provided at runtime.

Using an expression:

CONCAT("Invoice #", invoiceNumber)

prints:

Invoice #12345

Formatting values​

In many cases, raw values are not enough.

For example:

  • a number should look like a price
  • a name might need a prefix
  • a value might need to be combined or shortened

You can format values directly inside the Data (expression) field.

Instead of:

Amount

you can use:

CONCAT(NUM(Amount, 0, 2), " €")

This controls how the value appears in the final document.

Formatting text using expression

Common examples​

Combine multiple fields​

CONCAT(name, " ", surname)

Result:

John Smith

Add text around a value​

CONCAT("Invoice #", invoiceNumber)

Format numbers​

CONCAT(NUM(Amount, 0, 2), " €")
note

See full guide: Formatting Numbers

Format dates​

Dates are formatted using a dedicated function.

note

See full guide: Formatting Dates

Where this is used​

Formatting is applied directly in:

  • Text Box → Data (expression)

Each Text Box controls how its value is displayed.

Using + operator (alternative)​

In addition to functions like CONCAT(), you can also combine values using the + operator:

"Invoice #" + invoiceNumber

This produces the same result as:

CONCAT("Invoice #", invoiceNumber)

While both approaches are supported, CONCAT() is recommended for clarity and consistency.

Keep it simple​

Start with:

  • a simple field name
  • small adjustments (adding text, combining fields)

You don’t need to fully understand expressions to get started.
