Error using readtable: An error occurred while trying to determine whether "readData" is a function name

I get the following error when I am calling

readtable('file.csv')

Error using readtable (line 197)
An error occurred while trying to determine whether "readData" is a function name.

Note: readtable detected the following parameters:
'Delimiter', ',', 'HeaderLines', , 'Format', ''

Can you please help me on this one (do not provide me links on the same topic, I have checked everything and nothing is working) ?

hi

maybe you should share a copy of your csv file to let us check the issue

The error looks unusual from the "readtable" function. It could be due to several reasons. Try the following steps:

• Ensure that the file path is correct and the file exists at the specified location.

filePath = 'file.csv';
if exist(filePath, 'file') ~= 2
    error('File does not exist at the specified path.');
end

• Sometimes, MATLAB's path can get corrupted. Resetting it to the default state can help.

restoredefaultpath;
rehash toolboxcache;

• Try specifying the delimiter and other parameters explicitly in the "readtable" function.

opts = detectImportOptions('file.csv', 'Delimiter', ',');
T = readtable('file.csv', opts);

• Ensure that the file content is properly formatted and does not contain any unexpected characters or missing values that could cause issues.
• Clear any functions and variables that might be interfering with "readtable". You can use the following command to see the specific function being called:

which readtable

• If "readtable" continues to fail, try using "readmatrix" or "readcell" as alternatives to read the data.
