Summary

This operator allows to import data from a text file where values are separated by comma (comma separated values, CSV) or another symbol.

It can only be applied to an empty data node.

The text file has to be available in the TIS File on the TIS Server. Therefore, a file from a local storage has to be uploaded to the TIS Server.

Import via Parameters	As of version 5.8 import files can be defined via Parameters.
Error Node	As of version 5.8 a specific error node can be defined. This way, error nodes can be displayed in TIS Board. The error node contains data rows that could not be properly interpreted. Create an empty data node and choose the node as error node in the operation settings.

Imports data from a text file.

Examples

Example: Import text file of the type "Date/Time/Time"

Situation	The text file Import_1.txt is to be imported into a data node.
Step 1	Go to Editor Homepage and choose the TIS File tab; upload file.
Step 2	Create an empty data node. To this node, add the operation "Import Text or CSV file 3.0". Click on the folder symbol next to "Name" and select the import file. Alternatively, files can be defined via parameters under "Path (manual):" Then choose the following settings: Then click "Execute" to let TIS suggest the columns based on your suggestions. You will need to correct the suggested column "Bis" to Semantics: "Time (end)". You get into the editing mode by clicking the icon You need to confirm changes by clicking the icon Columns that are not supposed to be imported can be deleted with the icon You can change the order of columns (how they will be displayed in the result table) with the icons und As of version 5.8 a specific error node can optionally be defined. That gives the possibility that error nodes can be displayed in TIS Board. Create an empty data node and choose the node as data node in the import operation.
Result
Further steps	The resulting table should be converted to date+time/date+time to allow operations such as Scaling 8.0.

Example 2: Import file of type date+time/date+time

Situation	Read in the text file Import_2a.txt First, save the file on your PC and then import it into TIS (see TIS:Datenmanagement (link to old wiki)). Create an empty node in the TIS project and add operation "Import text or csv-file".
Operation setting	Click on the folder symbol next to "Name" and select the import file. Alternatively, files can be defined via parameters under "Path (manual):" Then, chose the following settings: Click "Execute" to let TIS suggest the columns based on your suggestions. You will need to correct the suggested column "Bis" to Semantics: "Date+Time (end)". Please note: Click on the button "Edit" to change settings. Click on the button "Apply" to confirm changes. As of version 5.8 a specific error node can optionally be defined. That gives the possibility that error nodes can be displayed in [TIS]Board. Define an empty data node and choose the node as data node in the import operation.

Example 3: Import file of type date+time/date+time with overlap to the next day

Situation	Read in the text file Datum;Von;Bis 01.01.2007;06:00;14:30 02.01.2007;06:00;13:00 03.01.2007;14:00;23:00 04.01.2007;14:00;22:00 05.01.2007;22:00;06:00 06.01.2007;22:00;06:00 09.01.2007;06:00;14:00 10.01.2007;06:00;15:00 11.01.2007;06:00;25:00 12.01.2007;06:00;05:00+ 13.01.2007;06:00;06:00+ 14.01.2007;22:00;0600 Please note: Times overlapping to the next day are indicated by different formats here: 25:00, 5:00+, and 600. This example will demonstrate how to read in each of these formats.
Operation setting	One solution for this is to apply the Formula operator (row-by-row) (4.0) = Formeloperator to create new columns which calculate the correct date and time: Formulas are: 1. NextDay [Ja/Nein]: #Bis#.Substring(#Bis#.Length-1 > 0 ? #Bis#.Length - 1 : 0) == "+" \|\| #Bis#.Contains("") 2. Bis2 [Text]: #Bis#.Replace("+","").Replace("",":") 3. h [ganze Zahl]: System.Convert.ToInt32(#Bis2#.Split(':')[0]) 4. m [ganze Zahl]: System.Convert.ToInt32(#Bis2#.Split(':')[1]) 5. Bis3 [DateTime]: #Datum#.AddDays(#Nextday# ? 1 : 0).AddHours(#h#).AddMinutes(#m#) 6. Von2 [DateTime]: #Datum#.Add(#Von#.TimeOfDay)

Troubleshooting

Problem	Frequent Cause	Solutions
Everything is suggested as Identifier although I wanted to read in Text.		This can be changed manually, but it is usually not necessary. All operations which work with Text, also work with Identifier. (Identifier = special case of text) If columns remain after conversion, and this is not wanted, simply delete those columns.
How can I make changes to the "Mapping" table?		You get into the editing mode by clicking the button You need to confirm changes by clicking the button Columns that are not supposed to be imported can be deleted with the button You can change the order of columns (how they will be displayed in the result table) with the buttons und
"Execute" is suggesting only 1 column with all column titles in "Mapping"	Commong error: Wrong column separator has been chosen (e.g., semicolon instead of tabulator)	Check column separator, change it and click "execute"
The operation does not read in the decimal points (or not in every column)	Decimal symbol has not been selected correctly. After clicking "Execute" the suggested columns have been applied without further checking. However, TIS interprets the values in the import table by reading the values in the first row. If the first row contains numbers without decimal numbers, TIS suggests Integer as data type.	Check if the decimal symbol has been chosen correctly. Check the data type for each column. For decimal numbers you need to select "Double" as data type.
24:00 is not imported correctly	24:00 is no allowed format, because in most software systems it means that it is already the next day.	1. Trick: Replacement of illegal values in combination with formula operator: State in the import operation that illegal values should be replaced by 23:59:59: Then import, with replacement of illegal values. Convert the table to a date+time/date+time format with the Operation Convert "From-Date/From-Time/To-Time" Then, apply the Formula operator (row-by-row) (4.0) = Formeloperator and change the corrected date (attention: don't forget to choose Date as the data type) with the following formula: If the column that needs to be changed is named "Datum", then you can copy this formula: #Datum#.AddSeconds(#Datum#.Second == 59 && #Datum#.Minute ==59 && #Datum#.Hour==23 ? 1 : 0)
A time overlapping to the next day is included (e.g., 25:00)	25:00 is no allowed format, because in most software systems it means that it is already the next day.	Possible solutions please see Example 3 above Another trick: Use data type "Text" for time Resulting in:
Date has date-time format, although Data Format is set to Date (e.g., DMY)		Change semantics from Identifier (name) to Date
