Missing statements

[primuspaul]

I am analyzing some information from my old bank statements. There are many accounts and there are in no particular order (date or account #). So for each monthly statement (each statement could have one or more entries), I input the info that I needed and also included two columns: start date and end date. Is there a way to analyze this data to see what statements I have and what statements I am missing?

Please post a sample of your data and expected output.

account#    startdate     enddate
444555       1/1/13        1/31/13
444555       5/1/13        5/30/13
888888       1/22/14       3/21/14
888888       5/22/14       7/21/14

I expect a result that can help me easily conclude that I am missing 2/1/13 --> 4/30/13 for account 444555 and 3/22/14 --> 5/21/14 for account 888888. Unfortunately, statement beginning and end dates can vary and can be for varying periods of time. Some statements have cut offs in the middle of months. Others are monthly. Some are quarterly or bimonthly.

I saw some tutorials saying to do a gantt chart, but I'm having trouble getting it to work.

This does the trick:

However, it requires a fairly large amount of maintenance due to the extra tables it needs. I was wondering if there was something like an excel plugin/open source program to fully automate this.
