etlplus.file.fwf

etlplus.file.fwf module.

Helpers for reading/writing Fixed-Width Fields (FWF) files.

Notes

  • An FWF file is a text file format where each field has a fixed width.

  • Common cases:
    • Data files from legacy systems.

    • Reports with aligned columns.

    • Data exchange in mainframe environments.

  • Rule of thumb:
    • If the file follows the FWF specification, use this module for

      reading and writing.
