I have many files in this ascii format. The RRC has MAGNETIC TAPE USER GUIDE with field descriptions that contain beginning and ending positions. I have attempted to use the schema mapper with csv file that describes this but have yet to figure out how to make that work.

please help,

Files are located here.

fileThe file looks like this...

formatThe format description is like total bytes per record 308 bytes.

@Brad Nesom​ Thanks for including the sample data. These look like Texas Railroad Commission (RRC) data files. We have configured FME to read some of the record types for these files before. A specification similar to the attached PDF specification usually accompanies these files - can you attach the PDF spec for you data?

The approach we took was a two- step process:

  • formatting: use information derived from the PDF data spec. to create some 'format' files that FME can read. These represent the schema of the source data and then how it can be written out as a more easily interpreted CSV file. For each RRC record type we created an AttirbuteSplitter format string
  • Convert to CSV: using the configuration files above convert to pipe (|) delimited CSV for easier interpretation. These are then easier to convert into the target format.

The trick to the whole thing was creating the formatting files. The data we worked with doesn't seem to match the data you have attached.
