I have two csv file WT and both have fixed have 52 header. I tried to use below command to read however header is as Var1,Var2..to Var52 instead of Store no,Date and Time. How can I fix the header problem with importing all the datas from those files? Using opts = detectImportOptions()

table = readtable('WT_201120.csv'); 
table1 = readtable('WT_.csv');

Note that your files are formatted differently: the file WT_201120.csv contains each header line quoted within one pair of double quotes, i.e. as one text field. The other two files have many separated fields (some of which are text).

Have you used Excel to manipulate any of those files? Which file uses the correct, original format?

在 MATLAB Online 中打开

Here is the solution - data range specified and Variable names set true:

DATA1 = readtable('WT_201120.csv', 'Range','A38:AZ6684', 'ReadVariableNames',true);
% Similarly for the other csv data file.

Note that all column headers are not placed in your csv data except for the first one (Store__No ....). You need to fix this issue in your data file and then import it into MATLAB.
