Answer 1

What's happening when you pass "0001" into a spreadsheet is the same thing that would happen if you typed that number into the spreadsheet from the Excel application. It converts the internal storage to "number". If you want to preserve exact text, add a single quote mark before the text, e.g. "'0001". (or {'''0001'} for cells.) This is the same thing you'd need to do if you tried tying the number into the Excel application to preserve the leading zeros.

This only happens on Windows when communicating with an active Excel process. If you're in the most recent release, you can also use the "UseExcel",false parameter, which won't do any post processing to the text; it is stored as-is. If you do, however, opening the file in Excel and re-saving might modify the contents.

So I am using a Mac but the OP maybe using windows which may be the effect of this you say?

Use xlswrite() or writetable().

Charalambos Charalambous's answer moved here:

Hi Madhan

I do use xlswrite. The goal here is to add subject's id number (eg. 0001) in the fisrt collumn of each tab.

the code that i am using is

subjectid = cellfun(@num2str,{'0001'},'un',0)

xlswrite('temp.xlsx',subjectid)

But as you can see in the attached file, the exported value is '1'.

It would be great if i am able to export this value as '0001' from matlab to excel.

Any help would be very appreciated.

Try the below:

a={'0001'}
writetable(table(a),'xxx.xlsx')

Hi,

Thank you for the code; however, stil the same issue. It seems that excel does accept 0s before a number. Is this true?

[madhan ravi]

What do you mean? Did‘nt my comment do what you asked for ?

Answer 4

[ccc7]

unfortunately no. see attached file. A2 cell = '1'

[madhan ravi]

I haven‘t checked the excel file but the data is preserved. Try

readtable('xxx.xlsx')

Answer 5

[ccc7]

what version do you use? I am using 2017b. Still does not work.

[madhan ravi]

I use 2018b:

>> a={'0001'}

a =

  1×1 cell array

    {'0001'}

>> writetable(table(a),'xxx.xlsx')
>> readtable('xxx.xlsx')

ans =

  table

      a   
    ______

    '0001'
