You may be exporting data from an accounting tool into an .XLS format (Excel spreadsheet) every month, and then manually searching, cleaning, and replacing values. More specifically you probably spend a lot of time finding and replacing duplicates, and performing advanced operations such as a VLOOKUP or a QUERY function in order to pull data from other sheets or digging through records that use unfriendly date timestamps.
In this article TechandEco walks us through how to automate this monthly task by using a Google macro and a custom menu, and invite you to try it out yourself. In the future, you can convert your Excel into a Google Sheet by dragging it or uploading it into a folder in your Google Drive>then second click the file to view its options > open as > Google Sheet.
