Hello @tim_tsang
Which API that you are using? By default, the Eikon Data API returns data as Pandas DataFrame object or raw JSON message format. These data type can output to console, application, file, etc.
Please refer to Eikon Data API quick start guide, tutorial and reference guide.
@wasin.waeosri I am using Codebook (Python 3)
Could you please give me more detail regarding your question and requirement? Do you want to export the Codebook output (DataFrame, JSON, etc) to somewhere else?
