DIF (Data Interchange Format) is a text-based file format for spreadsheet and tabular data. It is now primarily used for data exchange between spreadsheet programs.

The general-purpose commands Import and Export also support this format.

The default output from Import for this format is a DataFrame. To produce a Matrix, use Import(...,output=Matrix).

$\mathrm{Import}\left(''example/timeline.dif''\,\mathrm{base}=\mathrm{datadir}\right)$

$\mathrm{Import}\left(''example/timeline.dif''\,\mathrm{base}=\mathrm{datadir}\,\mathrm{output}=\mathrm{Matrix}\right)$

$M≔\mathrm{LinearAlgebra}:-\mathrm{RandomMatrix}\left(100\,2\right)\:$

$\mathrm{Export}\left(''example.dif''\,M\,\mathrm{base}=\mathrm{homedir}\right)$

$2482$

With Maple 2016, the Import command applied to DIF files now produces DataFrame objects by default.
