My first Google sheets add-on is published! To be totally honest, I made it mainly to see what was involved. I really like the work that Andrew Stillman has been doing with New Visions for Public Schools, including Doctopus and formMule, and I wanted to see if I could do similar things for higher ed or international ed.
My add-on is called Text Adder, and it pretty much just does what the name indicates. Once it’s installed, the user can select a range of cells, and Text Adder will add a chosen text to the beginning or end of every cell in the range.
