How do I remove NaN values from a cell array?

I'm editing some code I was given to read in spreadsheet data collected in the field into Matlab. Some of the cells in these spreadsheets are merged, and so when I read those in, I get cells that look like ['number' 'NaN' 'number' 'NaN' ...]. I want to convert the cells to matrices, but cell2mat doesn't work when the cells contain data other than numbers. I'm trying to use "rmmissing", but get the following error:

I suppose the obvious solution would be to unmerge the cells in the spreadsheets, but there's a lot of them, and I want to see if there's a quicker way I can do this in Matlab once that data is imported.

The presence of NaNs isn't the problem. The problem is that the cell contents are character vectors of different lengths. You can convert them like so,
>> str2double({'1','2';'NaN','40'})
ans =
1 2
NaN 40
