I have 2 sets of accounting data to check, one from the bank statement, and the other is my internal company financial statement. Both sets use different different formats to present the financial data. When doing bank recon, I need to check a specific amount that appeared in the bank statement, its corresponding location (ie same amount etc) that appear in our internal company financial statement. May I know what is the most most efficient way to do this? Currently, I do manual check. I was told that I can do vlook or match, but I do not know how to do it. I am not good that excel functions. I am just a basic beginner excel user. Thanks.
