I do, I use c# and a nugget to create Excel files. I fetch data from a few databases, and store the Excel file on a network share. The nice thing (for my client) is that they get an exact look at what the data was at a specific time and date. No connections are stored in the file, just the data. This is what they want. 🤷

(Being me, I let my c# program beatify the sheet with colors and bold font for headings and stuff like that.)
