Formula - removebom

Easily remove BOM (Byte Order Mark) characters from messages using the Nodinite removebom Formula plugin. This page shows how to strip BOM markers from message Content, or the output of other formulas.

🎯 Designed for business users and integrators — no developer required; you can even use AI to craft expressions.

  • ✅ Remove BOM characters from any Payload or Context in any Log Event
  • ✅ Clean text data to ensure proper processing downstream
  • ✅ Transform and surface meaningful data in Nodinite Log Views, search filters, and self-service diagnostics
  • ✅ Combine with other Formula functions for powerful, layered expressions

What does the removebom Formula do?

The removebom(Content) Formula function removes the Byte Order Mark (BOM) character from the beginning of text. Use it on message bodies, context values, or the results from other Formula functions to clean data for your views.

How it works: Input ➜ removebom ➜ Result

graph LR A["Input: Text with BOM"] --> B["removebom(Content)"] B --> C["Result: Clean text without BOM"]

Diagram: The removebom function processes content to remove the BOM character from the beginning.

Syntax

Remove BOM from message body: (See Example 1)

removebom(body)

Remove BOM from message context: (See Example 2)

removebom(context('MessageContextKey'))

Remove BOM from nested formula: (See Example 3)

removebom(jsonpath('$.path', body))

Examples

Example 1: Remove BOM from the message body

Input:

Message body is 0xEF0xBB0xBFnodinite

Formula Expression:

removebom(body)

Result:

nodinite

Example 2: Remove BOM from message context

Input:

Message context contains a property data with value 0xEF0xBB0xBFdata

Formula Expression:

removebom(context('data'))

Result:

data

Example 3: Remove BOM from nested formula result

Input:

Message body with extracted value is 0xEF0xBB0xBFvalue

Formula Expression:

removebom(jsonpath('$.data', body))

Result:

value
