How it works

Complete the job in three clear steps

  1. Add CSV data and duplicate-matching rules.
  2. Choose the relevant options and create a deduplicated CSV.
  3. Review the result, then copy or download it when available.

Important

Check the result before relying on it

Review generated output before using it in production. Formatters and converters can validate structure, but they cannot understand every application-specific rule or guarantee that transformed content has the intended meaning.

Questions

About this tool

Does this tool upload my working data?

No. The workspace processes its input in this browser and does not send the working content to Lucaden.

Should I verify the result?

Yes. Keep important originals and check generated files, codes, calculations, and transformed data in the system where you plan to use them.
