Use an import options object to configure how readtable interprets your file. Compared to name-value arguments, an import options object provides more control, better performance, and reusability of the file import configuration. Import the contents of a text file into a table. The resulting table contains one variable for each column in the file and uses the entries in the first line of the file as variable names. Create a table from a text file that contains data gaps.

Help Center Help Center. You can read data into tables interactively or programmatically. To interactively select data, click Import Data on the Home tab, in the Variable section. To programmatically import data, use one of these functions:. This example shows how to import spreadsheet data programmatically using both functions. The sheet names correspond to the year, such as Call readtable to read all the data in the worksheet called , and then display only the first 10 rows and columns. Specify the worksheet name using the Sheet name-value pair argument. If your data is on the first worksheet in the file, you do not need to specify Sheet. From the worksheet named , read only 10 rows of data from the first 5 columns by specifying a range, 'A1:E11'. The readtable function returns a by-5 table.

Row names must be in a single column.

A table consists of column-oriented variables, each containing data of the same type. Variables in a table can hold different data types and sizes, but each variable must have the same number of rows. You can customize aspects of the import using name-value arguments or an import options object. You can import tabular data from a text file into a table using the readtable function. For example, the sample file outages.

Help Center Help Center. The text file is indicated by the file identifier, fileID. Use fopen to open the file and obtain the fileID value. When you finish reading from a file, close the file by calling fclose fileID. The textscan function reapplies formatSpec throughout the entire file and stops when it cannot match formatSpec to the data. To read additional data from the file after N cycles, call textscan again using the original fileID. If you resume a text scan of a file by calling textscan with the same file identifier fileID , then textscan automatically resumes reading at the point where it terminated the last read.

If "DatetimeType" is specified as "text" , then the type for imported date and time data depends on the value specified in the "TextType" parameter:. To interactively select data, click Import Data on the Home tab, in the Variable section. Date ind. Example: "Range" , "A1:F10". Select the China site in Chinese or English for best site performance. You also can use the output of a function as a variable name. For example, store the values as signed bit integers. An import error occurs when readtable is unable to convert a text element to the expected data type. Expected number of variables, specified as ExpectedNumVariables and a positive integer. If you specify the "Encoding" argument in addition to the import options, then the readtable function uses the specified value for "Encoding" , overriding the encoding defined in the import options. Value of "BinaryType" Data Type of Output Table Variables "auto" data type detected automatically "text" unaltered input text "int8" 8-bit integer, signed "int16" bit integer, signed "int32" bit integer, signed "int64" bit integer, signed "uint8" 8-bit integer, unsigned "uint16" bit integer, unsigned "uint32" bit integer, unsigned "uint64" bit integer, unsigned.
