Timothy Gilbert

Timothy Gilbert

Excel VBA Programmer

United States - Tests: 6 - Portfolio: 3

The best way I can help you is by taking the tasks you have to perform repetitively in Excel and turning them into macros and programs that can be run quickly and easily at the push of a button. I have done everything from simple scripts to separate name fields, to reformatting and combining monthly financial data into year end reports, to an entire ship design analysis program inside of Excel. I can make macros that run from buttons, hot-keys, whenever a cell is changed, or on a timer. I can have excel files export to or import from other excel files to combine different data sets. Some macro types: Data lookups (for searches too complicated to do with VLookup and index/match). Data cleanup (splitting names/combining fields/replacing text). Downloading images from URLs or matching images in a folder based on a text in the filename. Creating cross-references and combining or removing duplicates. Time/project/inventory management. I've also done some other windows application programming such as a program to list potential music keys from a set of notes, and a 2D procedural world generator program with tectonics and erosion simulations. I have experience in Photoshop for graphics, logos, and photo retouching.
