[2.0.1] 2023-07-11


  • Export Service now supports JSON Lines inputs that don't have a trailing empty line. Before this version, the Export Service ignored the last line of JSON Lines inputs, assuming that it would be an empty line.



  • Service has been totally rewritten in NodeJS
  • All export formats are now generated in streaming, which makes very large exports possible
  • The columns field is no longer required in the /export request body. If a column is not present in the input data source the result will include it as an empty string. If not specified, all columns present in the input source will be exported according to the default JavaScript property order (numbers in ascending order followed by strings in insertion order). If specified, csv, html and xlsx exports will also include a header row specifying the exported column names.
  • The contentType field is no longer accepted in the /export request body. The response Content-Type header value is now inferred from the export type field.
