Congrats on the release! LibreOffice was one of the first large applications I looked at, mostly due to my interest in spreadsheets generally. I generally have massive respect for anyone / anything that can parse a legacy Microsoft file format. [1]

My interest in spreadsheets lead to me making https://trymito.io. Check it. We’re a spreadsheet that sits inside a Jupyer notebook, allowing you to write spreadsheet formulas and generate equivalent Python code. Feedback greatly appreciated!
