Readmatrix reading csv files incorrectly by replacing values with NaN and adding a third column

Hi all,

I have 10 ".csv" files which I am importing into MATLAB using the readmatrix function. All of these files are identical as follows:

Rows: 1000001 - First row has headers (Time [s], Volts [V]))

Columns: 2

All but two files are not being imported correctly. I have tried opening them in text editors to verify the comma delimiter and it is correct. I do not know what the issue is. For these two files, MATLAB reads the second (Volts) column as NaN and adds a third NaN column to it.

Kindly please help.

The line of code I am using is: variable_x = readmatrix('filename');

A short excript is as follows:

Important to note that I have also tried the 'range' and 'delimiter' options explicitly to no avail. Might be a bug. I am using R2023b

Hi @Mohid Muneeb - well please attach the "problematic" files...

Edit: nevermind, I found the issue. There were two cells out of a million with problematic data in the .csv files I had issue with. I used the "csvread" function to locate this since the error it outputs tells the exact cell that has the problem as well as its actual text.
