Do you use spreadsheets? Absolutely! For many different things.
What is your go-to spreadsheet program? Excel
Do you have any really complex ones? I have a couple that I downloaded from template websites that have some of the more advanced features that I've never learned.
Any spreadsheet tips or tricks? If you want to learn more, check out the YouTube Channel from Chester Tugwell. He has loads of videos on Excel and Word. He also has videos for Google Docs and Google Sheets.
I first taught myself about spreadsheets in the late 1970's using a program called MultiPlan. It was the precursor to Excel. I also used Quattro Pro which was the version of a spreadsheet developed by a company called Borland. It is now the default spreadsheet in the Word Perfect suite of products sold by Corel (now Alludo). When I first went to college, spreadsheets were an unknown thing and neither were personal computers! When I went back in the 1990's to get an accounting degree, I had to take a computer class on Excel. I had been working with Excel so it was an easy A. After graduation when I worked in a CPA firm, we used the Microsoft products and the job after that which I retired from after 16 years also used the Microsoft products. So I've used Excel for over 35 years. I do have a subscription to Microsoft 365 just for the Excel program so I always have the updated version.
Besides financial information (checkbook, envelope register and budget spreadsheet), I have quite a few spreadsheets for my scrapping. One is used to track digital supplies used. Another one is where I set up how I set up a Shutterfly book. I use that same spreadsheet to track which layouts I have done for my cousin and what ones I still need to do. I have several spreadsheets for medical bills especially since I have 2 insurances that I get EOB's for. Needed to have a way to match them up. There are so many more that I have that I won't go into. Excel is open on my desktop all day long, that's how much I use it.
I've said for years (and did a layout over 10 years ago)... I'M A SPREADHSEET JUNKIE!!!!
