The Text file output step is used to export data to text file format. It is also possible to generate fixed width files by setting lengths on the fields in the fields tab. It is not possible to execute this step on parallel to write to the same file. In this case you need to set the option "Include stepnr in filename" and merge the files later on.

This field specifies the filename and location of the output text file. Don't add the extension in this field, when the date and time should optionally be appended and afterwards the extension option see Extension option field below.

When the Extension option is left blank, add it to this field. Enable to "pipe" the results into the command or script you specify. It can also be used for some database bulk loaders that can process the input from stdin. In this case set the filename to the script or binary to execute. Enable this option to return the data via a web service instead writing into a file see PDI data over web service.

Enable to avoid empty files when no rows are getting processed. When the previous option is enabled, you can specify the field that will contain the filename s at runtime.

If you run the step in multiple copies Launching several copies of a stepthe copy number is included in the filename, before the extension. This adds all processed filenames to the internal result filename set to allow for further processing. This option shows a list of the files that will be generated. This is a simulation and among others depends on the number of rows that will go into each file. Specify the character that separates the fields in a single line of text. Typically this is ; or a tab.

A pair of strings can enclose some fields. This allows separator or enclosure characters in fields. The enclosure string is optional. This option forces all fields of an incoming string type independent of the eventually absolute fastest way to save and read data from text file orbinary file field type within the Text File Output field definition to be enclosed with the character specified in the Enclosure property above.

This is for backward compatibility reasons since version 4. The logic since version 4. When a absolute fastest way to save and read data from text file orbinary file field contains an enclosure it gets enclosed and the enclose itself gets escaped. When a string field contains a separator, it gets enclosed. Check this option, if this logic is not wanted. It has also an extra performance burden since the strings are scanned for enclosures and separators.

So when you are sure there is no such logic needed since your strings don't have these characters in there and you want to improve performance, un-check this option. Enable this option if you want the text file to have a footer row. Last line in the file. Be careful to enable this option when in Append mode since it is not possible to strip footers from the file contents before appending new rows.

There are use cases where this option is wanted, e. UNIX files have lines are separated by linefeeds. DOS files have lines separated by carriage returns and line feeds. Specify the text file encoding to use. Leave blank to use the default encoding on your system. On first use, Spoon will search your system for available encodings. Allows you to specify the type of compression. Only one file is placed in a single archive. Add spaces to the end of the fields or remove characters at the end until they have the specified length.

Improves the performance when dumping large amounts of data to a text file by not including any formatting information. If this number N is larger than zero, split the resulting text-file into multiple parts of N rows. The fields tab is where you define properties for the fields being exported.

The table below describes each of the options for configuring the field properties:. The format mask to convert with. See Number Formats for a complete description of format symbols. The trimming method to apply on the string. Trimming only works when there is no field length given. Alter the options in the fields tab in such a way that the resulting width of lines in the text file is minimal. So instead of savewe write 1, etc. String absolute fastest way to save and read data from text file orbinary file will no longer be padded to their specified length.

All fields of this step support metadata injection. You can use this step with ETL Metadata Injection to pass metadata to your transformation at runtime. Which is kind of annoying, as files could rotate based on name changes such as Add But when initially each file is created it should write a header.

Although a footer is more complicated. Pentaho Data Integration Steps. A t tachments 0 Page History. Description The Text file output step is used to export data to text file format.

Options File Tab The File tab is where you define basic properties about the file being created, such as: Option Description Step name Name of the step. This name has to be unique in a single transformation. Filename This field specifies the filename and location of the output text file. Run this as a command instead? Pass output to servlet Enable this option to return the data via a web service instead writing into a file see PDI data over web service Create parent folder Enable to create the parent folder Do not create file at start Enable to avoid empty files when no rows are getting processed.

Accept file name from field? Enable to specify the file name s in a field in the input stream File name field When the previous option is enabled, you can specify the field that will contain the filename s at runtime. Extension Adds a point and the extension to the end of the filename.

Include partition nr in filename? Includes the data partition number in the filename. Include date in filename Includes the system date absolute fastest way to save and read data from text file orbinary file the filename. Include time in filename Includes the system time in the filename. Specify Date time format Enable to specify the absolute fastest way to save and read data from text file orbinary file time format Date time format Chose the date time format to append to the filename Add file name to rest This adds all processed filenames to the internal result filename set to allow for further processing.

Show filename s This option shows a list of the files that will be generated. Option Description Append Check this to append lines to the end of the specified file. Separator Specify the character that separates the fields in a single line of text.

Enclosure A pair of strings can enclose some fields. Force the enclosure around fields? Disable the enclosure fix? Header Enable this option if you want the text file to have a header row. First line in the file.

Footer Enable this option if you want the absolute fastest way to save and read data from text file orbinary file file to have a footer row.

Compression Allows you to specify the type of compression. Right pad fields Add spaces to the end of the fields or remove characters at the end until they have the specified length. Fast data dump no formatting Improves the performance when dumping large amounts of data to a text file by not including any formatting information. Add Ending line of file Allows you to specify an alternate ending row to the output file.

Option Description Name The name of the field. Type Type of the field can be either String, Date or Number. Format The format mask to convert with. Length The length option depends on the field type follows: Number - Total number of significant figures in a number String - total length of string Date - length of printed output of the string e.

Null If the value of the field is null, insert this string into the textfile Get Click to retrieve the list of fields from the input fields stream s Minimal width Alter the options in the fields tab in such a way that the resulting width of lines in the text file is minimal.

Read and write a file using a StorageFile object. Also see the File access sample. You can learn how to get a file by using a file picker in Open files and folders with a picker. Here's how to write to a writable file on disk using the StorageFile class. The common first step for each of the ways of writing to a file unless you're writing to the file immediately after creating it is to get the file with StorageFolder. First, call ConvertStringToBinary to get a buffer of the bytes based on an arbitrary string that you want to write to your file.

First, open the file by calling the StorageFile. It returns a stream of the file's content when the open operation completes. Next, get an output stream by calling the GetOutputStreamAt method from the stream. Put this in a using statement to manage the output stream's lifetime. Now add this code within the existing using statement to write to the output stream by creating a new DataWriter object and calling the DataWriter.

Lastly, add this code within the inner using statement to save the text to your file with StoreAsync and close the stream with FlushAsync. Here's how to read from a file on disk using the StorageFile class. The common first step for each of the ways of reading from a file is to get the file with StorageFolder.

Then use a DataReader object to read first the length of the buffer and then its contents. Open a stream for your file by calling the StorageFile. It returns a stream of the file's content when the operation completes. Get an input stream by calling the GetInputStreamAt method.

Put this in a using statement to manage the stream's lifetime. Specify 0 when you call GetInputStreamAt to set the position to the beginning of the stream. Lastly, add this code within the existing using statement to get a DataReader object on the stream then read the text by calling DataReader.
