toLowerCase

Description

Converts all alphabetical characters in a string to lowercase.

Syntax

Like many functions in DataPrime, toLowerCase supports two notations, function and method notation. These interchangeable forms allow flexibility in how you structure expressions.

toLowerCase(value: string): string

(value: string).toLowerCase(): string

Arguments

Example

Normalize UUIDs for comparison

Consider the following document:

{
    "uuid1": "37367559-35f4-459c-943e-19025765da15",
    "uuid2": "37367559-35F4-459C-943E-19025765DA15"
}

A direct comparison would fail due to differing cases. Use toLowerCase to normalize them:

filter toLowerCase(uuid1) == toLowerCase(uuid2)

filter uuid1.toLowerCase() == uuid2.toLowerCase()

Output

{
    "uuid1": "37367559-35f4-459c-943e-19025765da15",
    "uuid2": "37367559-35F4-459C-943E-19025765DA15"
}
