Yes, I suggest you use a fund transfer company like OFX rather than bank to bank direct transfers. My experience is that you get MUCH much better rates than the banks offer and the service is quick, efficient, easy to use and safe. ask around about the best companies to suit your purpose... I transfer OZ dollar to Thai Baht.
Try the Bangkok Bank I opened my original account with them. Orn and I were married at the time I opened the account. I do not remember that being a requirement to having an account though.
UP-date on my visa issue. Today I was issued a visa extension stamp for my marriage visa (no new visa) (the original Visa extension lapsed on the 4th Jan 2021) I was in and out in 5 minutes... Not a word was spoken... No eye contact made... I was NOT charged for the 1 year visa extension. I think someone from Head Office must have had a word in the ear of the local office. Once out of the office, as kindly suggested here, I carefully scrutinized the new extension stamp. This one has Thai WIFE written on it and goes until 28th Dec 2021 which is better than the 4th January because of the Thai New Year Holiday period. It has been a stressful experience but it is pleasing to see Immigration supporting their own published procedures.
Yes... that was why I wanted my existing 'SPOUSE' type 'O' visa extended. They yelled at me that I could not extend the original visa, had to apply here in Thailand and THEY, NOT AUSTRALIA!!! issued visas (the original Visa is a proper embossed Royal Thai Immigration Service visa) and disputed when I said I was entitled to ask for that to be extended literally yelling at me that I wasn't a lawyer and demanding how I knew. I said from the Royal Thai Immigration Web site... (we were in a Royal Thai Immigration office!!!) I suggested he look it up on their own web site... He demanded WE SHOW HIM so my wife googled Thai marriage Visa there in front of him and clicked on the Royal Thai Immigration Service Web Site and up popped the information that 12 month marriage type O visas could be and should be extended annually through a straight forward procedure at a Royal Thai Immigration Service Office in Thailand... Same conditions for renewal as for issuance... being properly married, living together and maintaining the bank account. He still refused to extend the visa and insisted we reapply for a new marriage visa.
