Import from Raw File¶

The Import raw task imports any file type in Rulex Factory in a single-column file format, without pre-processing it.

The task layout is made of two tabs: * the Options tab, * the Text Configuration tab.

The Options tab¶

The Options tab follows the structure shown in the Import Overview page.

The Text Configuration tab is divided into three panes:

Parsing options: here, users can find the parsing options.
Import options: here, users can find the import options.
Table preview: here, users can visualize a preview of their imported tables.

Within this pane, only one option is present:

Single row: if selected (default), the file will be imported in a single row. If it is not selected, each row’s values will be concatenated in the same column.

Within this pane, users can set the following options:

Start importing from line: the number of the line from which the import operations will start.
Stop importing from line (0 means all): the number of the line where the importing operations will end. Leave the value 0 if you want the whole dataset to be imported.
Add an attribute containing filename: if selected, an extra column with the name of the file is added to the dataset.
Strip spaces: if selected, it removes the empty columns from the imported dataset. For example, the string “ class “ will be imported as “class”.
Case sensitive: if selected, upper cases are considered different from lower cases.
Compress white spaces: if selected, it compresses contiguous occurrences of white spaces in one single occurrence. For example the string “university program” would be imported as “university program”.
Encode file content: select from the drop-down list the encoding which will be applied to the file before the import operation finishes. The possible values are Base64 and Hex.

The following example imports a flow stored locally to Rulex Platform in an encoded dataset format.

After having added an Import from Raw File task to the flow, double-click the task and configure it as follows:
- Select the path of the Local File System where the file is stored.
- Leave all the other options unchanged, making sure that the Single row option in the Text configuration tab is selected.
- Save and compute the task.

Add a Data Manager task to the flow or, alternatively, right-click on the task and select Take a look to visualize the results of the import operation.
