No columns to parse from file

When you receive the error message “no columns to parse from file,” it means that the system is unable to find any columns or headers in the input file that it can use for parsing data.

This error typically occurs when the input file is either empty or does not have a proper format that the system can recognize. It’s important to ensure that the file you are trying to parse has valid columns or headers to proceed with the parsing process.

Here’s an example to clarify the issue:

    
      File: example.csv
      -----------------
      John,Doe,25
      Jane,Smith,30
    
  

In this example, the system can detect three columns: “first name,” “last name,” and “age.” These column names provide a structure for interpreting the data within the file. If the file is empty or does not have these headers, the system will be unable to proceed with parsing.
