[Format="yyyyMMdd"]) то возвращает 20220131 А когда вставляю это выражение в работающий запрос = Json.Document(Web.Contents("https://bank.gov.ua/NBU_Exchange/exchange_site?start=20220115&end=Date.ToText(#date(2022, 01, 31), [Format="yyyyMMdd"])&valcode=usd&sort=exchangedate&order=desc&json")) то выдает ошибку Expression.SyntaxError: Ожидался токен Comma.

Да че там угадывать, в функцию надо передать строку, а в неё запихивают другую функцию по среди текста не отделяя

Using the IF(AND formula from excel as a reference, I am adding a coma after one of the nulls and one after the balance, but I am getting the error reference on the post title.
