#sorry if my english is bad
like i stated in the question. the readtable() function is error when i want to load .csv data.
this is strange because this morning i use it and is working fine. but when i using it this night is declare an error like this
>> csvData = readtable('asterix_cat48_2T1Searah1Berlawanan_ver2.csv')
Error using readtable (line 198)
Reference to non-existent field 'text'.
then i look up in the https://www.mathworks.com/help/matlab/ref/readtable.html#mw_19d8ece8-5151-47f4-8ff2-8e0fa633db25 for reference. and i look that there is a solution. the new line program that i use is like this
csvData = readtable('asterix_cat48_2T1Searah1Berlawanan_ver2.csv','Format','auto');
Error using readtable (line 198)
Reference to non-existent field 'text'.
Note: readtable detected the following parameters:
'Delimiter', ',', 'HeaderLines', , 'ReadVariableNames', true
but it make new error like that program said.
if you want to test it, you can download it in attachment that i give it.
i need help. thank you very much

Be sure to install the latest update to R2020a in your installation. It may be necessary to use 'PreserveVariableNames',1, or the name-value pair I use here. (I do not remember when that changed.)
In R2021a, it runs without error:
csvData = readtable('https://www.mathworks.com/matlabcentral/answers/uploaded_files/645870/asterix_cat48_2T1Searah1Berlawanan_ver3.csv', 'VariableNamingRule','preserve')
csvData = 59×52 table

Consider using readcell (introduced in R2019a) to read the file, then convert it to a table with cell2table.
.
ok thanks for the answer, and sorry for my late response. so this is absurd, i dont know its my fault or what. when i try again with the same program this morning
csvData = readtable('asterix_cat48_2T1Searah1Berlawanan_ver2.csv')
its working fine. i dont know why i get the error before. im not changing the file nor change the program, but now i think i will use the same program that i use before.
but thank you very much for the answer. if got the error again, i will try the solution that you gave.
