To import both the numeric data and the text data, specify two return values for xlsread. xlsread ignores a leading row or column of text in the numeric result. If you want to import only the numeric data, use xlsread with a single return argument. The Microsoft Excel spreadsheet file, tempdata.xls, contains two columns of numeric data with text headers for each column: Xlsread puts a NaN in place of the text data in the result.Įxample 3 - Handling Files with Row or Column Headers The Microsoft Excel spreadsheet file, testdata2.xls, contains a mix of numeric and text data. To read this data into MATLAB, use this command: The Microsoft Excel spreadsheet file, testdata1.xls, contains this data: Use this code to convert the dates to MATLAB dates. However, Microsoft Excel uses Januas the reference date and MATLAB uses January 1, 0000.įor example, if your Excel file contains these date values, Both Microsoft Excel and MATLAB represent dates as serial days elapsed from some reference date. When reading date fields from Excel files, you must convert the Excel date values into MATLAB date values. To determine the names of the sheets in a spreadsheet file, use xlsfinfo. Returns an error if sheetname does not exist. = xlsread('filename','sheetname') read sheet specified in sheetname. All cells that correspond to numeric data are empty. If the spreadsheet contains text that is not in a row or column header, xlsread returns a cell array the same size as the original spreadsheet with text strings in the cells that correspond to text in the original spreadsheet.

If the spreadsheet contains leading rows or columns of text, xlsread returns only those cells in B. = xlsread('filename') returns numeric data in array A, text data in cell array B. However, if a cell not in a leading row or column is empty or contains text, xlsread puts a NaN in its place in A. xlsread ignores leading rows or columns of text. xls)Ī = xlsread('filename') returns numeric data in array A from the first sheet in Microsoft Excel spreadsheet file named filename.
