Do you work with accounting or finance data? You are going to love, no scratch that, adore Power Query. It can save you precious time, make you look like a hero in-front of clients and keep you sane.
In this masterclass, learn all about Power Query for accountants (and other kinds of finance people) & 5 tips.
This is part of Power Mondays series, where every Monday we discuss Power BI / Power Query / Power Pivot.
Why Power Query?
Power Query is a data processing software. Using Power Query, you can create process driven programs (queries) to collect data, clean or reshape it, calculate things and publish final output as a table. Once you create a query in PQ, when the underlying data changes, you just refresh the query and brand new data will be fetched, cleaned and published for you.
For example, you can use Power Query to combine ledger files from various accounts to one master file with Power Query. No more VBA or manual copy pasting. Just one query and you are done.
