writing into excel sheets while keeping the leading zeros

10 views (last 30 days)
Hello, is there any way to keep the leading zeros in my number while saving to excel sheet as a csv file? I should be getting 000 001 010 011 etc but in the excel sheet it is 0 1 10 11. How can I solve this?

Isn't that down to the Excel formatting if it is a number rather than a string?

Following the:
you could use a similar method:
val1 = randi(1000,[20 1]);
val2 = rand(20,1);
val = val1.*val2
valWithZeros = num2str(val,'%09.3f')
valWithZeros = cellstr(valWithZeros)
for i=1:length(valWithZeros)
valWithZeros{i} = strjoin({'''',valWithZeros{i}});
Or pre-format your sheet and then copy the data to it from Matlab. If you need to repeat this action over many batches of data, make sure you first make a copy of the pre-formatted sheet and then overwrite it with Matlab:
Pre-formatted sheet:
The Matlab code:
val1 = randi(1000,[20 1]);
val2 = rand(20,1);
val = val1.*val2
