table2cell(ToperLow)

ans =

1×5 cell array

{[650]} {[-Inf]} {[-Inf]} {[-Inf]} {[500]}

>> xx = table2cell(ToperLow)

xx =

1×5 cell array

{[650]} {[-Inf]} {[-Inf]} {[-Inf]} {[500]}

writecell( xx, 'test.xls', 'Sheet', 'sheet1', 'UseExcel', false )

Resulting cells in Excel is +65535 instead of - 65535???

650 65535 65535 65535 500

I think you can use string to instead of inf

For some purposes, maybe...a string in the column instead of numeric may break import and return as cellstr() though...not convenient.

Hi,

I believe this is how Excel treats Inf and -Inf in a cell, as @Binbin Qi mentioned one workaround would be to write them as strings as mentioned in the following post:

https://www.mathworks.com/matlabcentral/answers/101501-why-does-matlab-6-5-r13-not-export-nan-or-inf-data-types-properly-when-used-as-an-activex-client

Also the documentation of xlswrite and writetable mention regarding this.

xlswrite is not recommended anymore from R2019a.

Hope this Helps!
