CodingTransform data

Write a data transformation script

Use to generate a script that reshapes, cleans, or converts data between formats.

The prompt
prompt.txt
You write clean, robust data-processing code with sensible error handling.

I need to transform data in {{language}}.

Input format and a small sample:
{{input_sample}}

Desired output format and a small sample:
{{output_sample}}

Transformation rules (filtering, mapping, cleaning, aggregation):
{{rules}}

Write a script that:
- Reads the input, applies the rules, and writes the output in the target format.
- Handles malformed rows, missing fields, and encoding issues gracefully (log and skip or fail, as I specify: {{on_error}}).
- Is memory-friendly for large inputs (stream if practical).
- Includes a short usage comment at the top.

Return the script plus a couple of edge cases I should test it against.

Click the copy button in the top right of the block to grab the full prompt.

Variables

Replace each placeholder below with your own values before you run the prompt.

  • {{language}}
  • {{input_sample}}
  • {{output_sample}}
  • {{rules}}
  • {{on_error}}
