txt2pajek: Converting text file data sets into Pajek format

Program by Jürgen Pfeffer, Vienna University of Technology

This program converts different types of text files into pajek .net files. The improvements compared to Excel2Pajek are:

• no size limits
• about 10 times faster than excel2pajek
• optional line values
• optional other line settings (e.g. color, line labels, …)
• works with different separators
• optional loops
• optional empty cells

How to do
Select the input file, select the separator (e.g. tab, comma, …). Now select the columns in which the data are contained. With the prefix and suffix option it is possible to add e.g. quotation marks ahead and after line labels or add a 'c' in front of a column with color information. Use '1' in line values if there are no line values but other line infos.

Additional Informations

• The option 'allow empty cells' creates a “*UNKNOWN*” vertex (in case of 2-mode: “*UNKNOWN1*” and “*UNKNOWN2*”).
• Multiple lines stay multiple lines.
• If there are any ” or ' (e.g. to identify text) they will be ignored.
