camelcase helper

Tom Santiago
Updated

Converts alphanumeric strings (uppercase and lowercase) to camelcase, and removes non-alphanumeric characters - including spaces, dashes, forwardslashes, and underscores. This is useful for creating variable-style keys or formatting labels consistently in integrations. Digits are preserved.

Usage

{{camelcase value}}

  • value (required): input string

Examples

  1. Convert a product type to camelcase

    {{camelcase record.product.type}}

    Input:

    {
  "record": {
    "product": {
      "type": "hand crafted item"
    }
  }
}

    Output:

    handCraftedItem

  2. Convert from dash-separated string

    {{camelcase record.category}}

    Input:

    {
  "record": {
    "category": "new-arrival-products"
  }
}

    Output:

    newArrivalProducts

  3. Preserve numbers and remove special characters from in a string

    {{camelcase "version-2_1-final"}} → version21Final

Tip

  • Numbers remain unchanged but are preserved in the output (e.g., "order_123_id" → order123Id).

  • All caps strings are switched to camelcase ("HELLO&WORLD" → "helloWorld")

  • Use this helper to standardize keys for APIs or when generating identifiers programmatically.

  • Unlike sentence, this helper does not add spaces or adjust casing beyond camelCase rules.

  • Non-alphanumeric characters (except digits) are treated as separators and removed

  • Leading and trailing whitespace is trimmed before conversion

  • Non-string datatype inputs (like numbers or boolean) are converted to strings before processing. Arrays of primitive types (like strings or numbers) are converted into a comma-separated string before processing. If inputs are objects or object arrays, the output will be unusable.
