![]() 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. Trailing rows and columns that do not contain data.Xlsread (MATLAB Functions) MATLAB Function Reference The importing functionĪutomatically detects the used range by trimming any leading and The spreadsheet that actually contains data. Note: Used Range refers to the rectangular portion of If unspecified, the importing function automatically detects Named ranges exist in a spreadsheet, then the importing function can For instance, you can select a rectangular portion of In Excel, you can create names to identify ranges in the Reading from the specified first row to the end of the data or the Importing function automatically detects the extent of the data by Specify the first row containing the data using the positive The specified range must match the number specified in the ![]() The row extent by reading from the first nonempty row to the end of Specified column range, the import function automatically detects Range by identifying the beginning and ending columns using Range, the importing function automatically detects the columnĮxtent by reading from the first nonempty column to the end of theĭata, and creates one variable per column. Specify the range by identifying the beginning and ending rows Specified range are imported as missing cells. Forĭata contained in the specified range. Start-row, start-column, end-row, and end-column. ![]() Using a four element numeric vector containing Opposing corners that define the region to read in Import 10 rows of the first 5 variables from the worksheet named '2007'.
