I have worked with MS Excel for 25 years and have developed a high level of competence with the use of the application, particularly with design and formula writing. I use formula writing not just to perform mathematical calculations but to execute logical instructions to create smart worksheets. A significant aspect of my Excel experience involved data import from other systems so I have become accustomed to handling more than a million records in MS Excel. This is why I always convert files in the old *.xls format to *.xlsx format, which can handle 1,048,576 records. There was a time I had to split a data set from a text file into three text files in order to import it into three separate worksheets in Excel because the data set contained just under three million records. In the same vein, I have become very accustomed to handling and navigating large batched of data in Excel. Finally, I have been given hard copy reports by a client, which I had to convert into electronic format to enter the data into Excel. I am happy to report that I have discovered an efficient method of converting hard copy data [presented in an array] into Excel format. I am confident that I will complete this project in the most efficient way and will add useful enhancements to the final worksheet.
