Hello everyone, I work on a DB that doesn't have much data inside, but it's a rather ramified DB because it collects data from company survey questionnaires and the different dimensions connected to them... The problem is that, by now, even when I simply modify the name of a field of a query, both power query and, even more, the upload of the changes in Power BI Desktop has become exhaustingly long: half hours pass!!!! I read another forum post where you talked about cleaning the data already knows Sql, but I don't use it: my sources are mostly excel sheets... I've already split the main query into several concatenated queries, with max 5 -6 passes each, but nothing has changed!!!!
