| Description: |
| I have a TXT/CSV - File using "|" (Pipe Symbol) as a Field Separator. There are about 1500 columns, I only need about 130 in a new file. I want to specify the source file, the used field (column) separator and the field (column) names for the columns I need in the target file. If it´s easier to look for the x-th occurence of the separator, I could also specify the column number instead of the column name, se example: Name, Mail, Extra or 1,3,6. Attention: Source file size is about 60 MB(!) |
| Input Sample: |
| Name|Address|Mail|Phone|Info|Extra Peter|Washington|pete@xy.com|1234|none|likes chocolate Amy|Detroit|amy@ab.com|9876|lalala|empty Henry|Nashville|hh@nv.com|4567|musician|country |
| Output Sample: |
| Name|Mail|Extra Peter|pete@xy.com|likes chocolate Amy|amy@ab.com|empty Henry|hh@nv.com|country |
