Thanks @rdwatters, unfortunately using external services like google sheets is not possible (would be great if they bring a similar feature to Excel/O365). I’ve gone through many different tools / processes to automate the conversion of Excel files to CSV. The constraints were that it has to work on a fairly locked down Windows environment with non technical users. The main issue I had was with “special” characters in spreadsheets and creating a UTF8 suitable CSV file for Hugo to read. Funnily enough, the most reliable solution I found was not actually using Windows, and installing Gnumeric via Windows Subsystem for Linux! (Gnumeric has a command line tool called ssconvert). However this dependency on WSL/Gnumeric felt a bit heavy, so I have recently gone back to a PowerShell module called ImportExcel (PowerShell modules can be installed by any user). Also, instead of converting to CSV, I am now converting to JSON which seems to be a more reliable format for Hugo.
