  2. Choose the settings for csv declared codebook recoder, then run the tool.
  3. Review the result and any limitations before copying or downloading it.

Good to know

  • 5000 CSV records,1000 distinct codebook entries and 1000 characters per code/label. Recoded text has a 300,000-character preflight.
  • Mappings use exact strings.500 unknown-code details and 20 witnesses per code are shown; full unknown-code counts remain visible. This does not infer a controlled vocabulary or validate a professional classification.
  • Processing is local. Output is limited to 1,000,000 text characters unless a stricter file limit is stated.

Common questions

Can two entries assign different meanings to the same code?

No. Duplicate source codes are refused before transformation, even if their target labels happen to agree.

Is this input sent to a server?

No. The application processes this input inside your browser tab and does not save it to persistent storage.
