Are you starting with a .csv file or a .xlsx file?
Are there multiple columns in the file? Should only one column be examined for a match? Should the entire row with the match be output? Is it possible that multiple rows will match?

data = readtable('FileNameGoesHere');
mask = data{:,ColumnNumberGoesHere} == 9;
subset = data(mask,:);
writetable(subset, 'sampletable.txt');

@Juan you again forgot to attach your data file and say what string pattern you're looking for. So that leads me to believe you did not read the Community Guidelines or Tutorial.
If you have any more questions, then attach your data and code to read it in with the paperclip icon after you read this:
