Typically this data is available as a plain text file organized into columns. MATLAB can easily handle tab or space-delimited text, but it cannot directly import files stored in the native binary format of other applications such as spreadsheets. Unfortunately, the load command requires that your data file contain no text headings or column labels.
Below I demonstrate both approaches with examples. I've included an m-file to handle the more complex case of a file with an arbitrary number of lines of text header, in addition to text labels for each column of data. Though hardly a cure-all, this function is much more flexible than the load command because it allows you to provide documentation inside your data file. The simplest, though least flexible, procedure is to use the load command to read the entire contents of the file in a single step.
The load command requires that the data in the file be organized into a rectangular array. No column titles are permitted. Toggle Main Navigation. Search Answers Clear Filters. Answers Support MathWorks. Search Support Clear Filters.

If you do not specify headerlinesIn , the importdata function detects this value in the file.
Data Types: single double int8 int16 int32 int64 uint8 uint16 uint32 uint Data from the file, returned as a matrix, multidimensional array, or scalar structure array, depending on the characteristics of the file. Based on the file format of the input file, importdata calls a helper function to read the data.
When the helper function returns more than one nonempty output, importdata combines the outputs into a struct array. This table lists the file formats associated with helper functions that can return more than one output, and the possible fields in the structure array, A. Other fields contain cell arrays of character vectors. For spreadsheets, each field contains a struct , with one field for each worksheet.
For more information about the class of each output, see the functions listed in Supported File Formats for Import and Export. If the ASCII file or spreadsheet contains either column or row headers, but not both, importdata returns a colheaders or rowheaders field in the output structure, where:. To import ASCII files with nonnumeric characters outside of column or row headers, including columns of character data or formatted dates or times, use readtable instead of importdata.
