Hello from Germany,
I’m pretty sure it will work. Most of the time people talk about whether s.th. is 220 or 110 Volt because this is the main difference. Sometimes in Europe we even say 220-240 Volt. 230 volt isn’t the exact voltage:
a quote from wikepedia about the u.k. for example:
“Voltage tolerance of 230 V +10%/−6% (216.2 V to 253 V), due to be widened to 230 V ±10% (207 V to 253 V) at a date yet to be specified”
