Multiple File Import can also import only one file. Table 2.5 can help you decide whether to use the standard Text Import, Multiple File Import, or JSL.
MFI does not guess. You specify the tab delimiters. There is no preview, but select Keep dialog open, and it is easy to try different import settings.
Try the JSL Open() function.
MFI understands PNG, JPG, and GIF files. You’ll get a table with a picture column.
Try the JSL Open() function.
MFI opens JMP, XLSX, and JSON files using JSL Open() and will stack them if requested. MFI does not keep the table and column scripts when it opens JMP tables, so you might need to use Files In Directory() and Open() if you need all of those scripts.
Select File > Import Multiple Files (Windows) or File > Open Multiple (Macintosh).
Browse to select the JMP Samples/Import Data folder.
In the Select Files by name or extension box, type UN*.csv and press Enter.

Click Import.

Keep dialog open is off by default, but you might turn it on while testing. This enables you to import files to see what the data looks like, edit the source files if necessary, and reimport them with the same settings.
