ConcatConst / String Layer

Concatenate (join) a string column with a constant text value. Similar to Python's string concatenation (str + str) or pandas string operations. Useful for:

Adding prefixes or suffixes to identifiers
Standardizing text formats (e.g., adding units)
Creating composite strings (e.g., full URLs, file paths)
Formatting display values

Table

Select

column

The source column containing strings to concatenate. The column must contain string values.

Value

string

The constant string (Value) to concatenate. Examples:

File extension (e.g., .txt)
URL prefix (e.g., https://)
Unit suffix (e.g., kg)
Delimiter (e.g., -)

Reverse

bool

false

If true, adds Value before the string from Select (prefix mode). If false, adds Value after the string (suffix mode). Example: with `Value='_test':

false: data -> data_test
true: data -> _test_data

Name for the new column. If not provided, the system generates a unique name. If AsColumn matches an existing column, the existing column is replaced. The name should follow valid column naming conventions.
