Field of Study: Technical
Presented by:  Jim Colville, CPA Retired, CFE

One of the pesky problems we run across in our work is duplicated data and how to deal with it.  We first have to identify the duplicate, decide if it’s really a duplicate and then deal with it.  This session is expanded in the May 12 webinar.

What is a Nano Session? Short presentations in increments of six minutes. Most of our nano webinars will be 10-30 minutes in length; this one being a full hour.  The purpose is to hit a topic and get into depth quickly, usually to help jump start you into a new topic and then repeat with new topic. Since this is fast moving and out-of-the-box the demo data files will be provided along with the needed notes.

  • Identify the possible duplicate, visually and with Excel features or functions
  • Is is really a duplicate? (San Diego Padres, The Padres, Padres, SD Padres, S.D. Padres)
  • Deal with it.  Delete it, Flag it, Delete and Archive for later reference
  • Prevent the duplicate in the first place
  • Internal data entry vs downloaded data.
  • The list goes on, you’re guaranteed to get a more than a full hour’s worth in this quick session.

All the files used in presenting these topics will be available for download before the webinar. The files will contain instructions on how to use the concept which includes the presenter’s notes.  The files will remain available online until March 31, 2021.

Jim Colville, Bio
Jim began working with spreadsheets with Lotus 1-2-3, v1a and then with Excel v3, and soon thereafter v4. He learned very early the power of Excel and how to be super productive in solving problems, creating business solutions and enhancing reporting in his CPA practice.

Seeing the business opportunity in educating others in using Excel he began his own PC training company teaching over 20,000 users over a period about four years. The training evolved into a consulting company offering specific solutions to companies and corporations by combining training combined with project challenges which resulted in powerful solutions. A by-product of this is Jim’s Zero Time Reporting, once the data is entered (or imported) the report is done.

Jim has authored well over Excel 500 courses, both as training materials and solution based Excel products for companies, corporations and nonprofit organizations. Many of these later became the foundation of web based articles and solutions under the the name of Info-Stat.com . With the saturation of Internet based Excel websites and Jim’s commitment to his CPA business the Info-Stat website was allowed to sunset. With his retirement from his CPA practice in 2019, Jim has revitalized his web-based activities in by writing articles, creating Excel files that offer solutions, revitalizing Info-Stat.com and more importantly, educational webinars through AEI. Excel has changed dramatically over the years and the new course and webinar offerings significantly modernize the Excel materials including, but not limited to, business and artificial intelligence.

Of major significance is the evolution of Jim’s education activities from a local San Diego PC training company to a national and world wide based company with Internet based products, both website and webinar offerings.
