I often save tables to Excel for sharing with others, but if the data is too large, I need to share to a CSV file instead. Here I build a function to do that. Features covered in this code-along style video include:
Note, at @18:13 I think I’m looking at the Excel file and don’t understand the first sheet name, but I’m actually looking at the CSV file and the sheet name defaults to the filename. You can ignore my floundering for the remaining 5 min of the video if you like.

Here is the code. I had to correct the possible Excel filename endings to .xls, .xlsx, or .xlsm.
function mywritetable(tableData,fileName,sheetName) % Writes table to Excel by default, but writes to CSV if too big and % appends sheetName to fileName maxRows=1e6; if height(tableData) < maxRows % Default: Write to Excel (assume xls, xlsx, or xlsxm extension) writetable(tableData,fileName,'Sheet',sheetName); else % If too big: Write to a CSV file fileName=regexprep(fileName,'(.xls|.xlsx|.xlsm)$',['_' sheetName '.csv']); writetable(tableData,fileName); end
