¿Cómo comprobar si un valor es alfanumérico?

Hola

Quiero comprobar si un valor tiene tres caracteres y los caracteres son alfanuméricos.

¿Cómo puedo comprobarlo, por favor?

Sería fácil con regex.

¡Gracias!

@UsePowerBI- ¿Desea una solución DAX o Power Query o le importa? ¿Y estás tratando de determinar si es numérico versus alfanumérico o estás tratando de averiguar que sólo contiene ciertos caracteres (a-z, A-Z, 0-9) y no caracteres como punto, punto y coma, etc.?

DAX is easy, CALCULATE makes DAX hard...

Si está en DAX:
ISERROR(VALUE("A23")) devuelve true, por lo que alfanumérico

ISERROR(VALUE("123")) devuelve false, por lo que

DAX is for Analysis. Power Query is for Data Modeling
