SAMHDA produces a tab-delimited ASCII data file (*.tsv) that can be used to import data into Excel. An example of a tab-delimited ASCII data file name is "34481-0001-Data.tsv", which can be downloaded for the National Survey on Drug Use and Health (NSDUH), 2011 study.
NOTE: An error will occur if you attempt to read in a data file that exceeds Excel's maximum row and column limits. Prior to Excel 2007, the maximum number of rows and columns in a single spreadsheet could not exceed 65,536 rows and 256 columns. From Excel 2007 through Excel 2016, the number of rows and columns increased to 1,048,576 rows by 16,384 columns.
