readtable

Create table from file.

Syntax

• T = readtable(filename)
• T = readtable(filename, opts)

Input argument

• filename - a string: filename source.
• opts - DelimitedTextImportOptions object

Output argument

• T - a table.

Description

T = readtable(filename) creates a table by importing column-oriented data from a text or spreadsheet file.

T = readtable(filename, opts) creates a table using the settings defined in the opts import options object. The import options object allows you to customize how readtable interprets the file, offering greater control, improved performance, and the ability to reuse the configuration compared to the default syntax.

Examples

Names = {'John'; 'Alice'; 'Bob'; 'Diana'};
Age = [28; 34; 22; 30];
Height = [175; 160; 180; 165];
Weight = [70; 55; 80; 60];
T1 = table(Names, Age, Height, Weight);
writetable(T1, [tempdir,'readtable_1.csv'])
T2 = readtable([tempdir,'readtable_1.csv'])

Names = {'John'; 'Alice'; 'Bob'; 'Diana'};
Age = [28; 34; 22; 30];
Height = [175; 160; 180; 165];
Weight = [70; 55; 80; 60];
T = table(Names, Age, Height, Weight);
writetable(T, [tempdir,'readtable_1.csv'])
options = detectImportOptions([tempdir,'readtable_1.csv']);
T1 = readtable([tempdir,'readtable_1.csv'], options)
options.DataLines = [1 Inf]
T2 = readtable([tempdir,'readtable_1.csv'], options)
