Dataset Card for "code_x_glue_cc_code_to_code_trans"

Dataset Summary

CodeXGLUE code-to-code-trans dataset, available at

The dataset is collected from several public repos, including Lucene(, POI(, JGit( and Antlr( We collect both the Java and C# versions of the codes and find the parallel functions. After removing duplicates and functions with the empty body, we split the whole dataset into training, validation and test sets.

Supported Tasks and Leaderboards

  • machine-translation: The dataset can be used to train a model for translating code in Java to C# and vice versa.


  • Java programming language
  • C# programming language

Dataset Structure

Data Instances

An example of 'validation' looks as follows.

    "cs": "public DVRecord(RecordInputStream in1){_option_flags = in1.ReadInt();_promptTitle = ReadUnicodeString(in1);_errorTitle = ReadUnicodeString(in1);_promptText = ReadUnicodeString(in1);_errorText = ReadUnicodeString(in1);int field_size_first_formula = in1.ReadUShort();_not_used_1 = in1.ReadShort();_formula1 = NPOI.SS.Formula.Formula.Read(field_size_first_formula, in1);int field_size_sec_formula = in1.ReadUShort();_not_used_2 = in1.ReadShort();_formula2 = NPOI.SS.Formula.Formula.Read(field_size_sec_formula, in1);_regions = new CellRangeAddressList(in1);}\n", 
    "id": 0, 
    "java": "public DVRecord(RecordInputStream in) {_option_flags = in.readInt();_promptTitle = readUnicodeString(in);_errorTitle = readUnicodeString(in);_promptText = readUnicodeString(in);_errorText = readUnicodeString(in);int field_size_first_formula = in.readUShort();_not_used_1 = in.readShort();_formula1 =, in);int field_size_sec_formula = in.readUShort();_not_used_2 = in.readShort();_formula2 =, in);_regions = new CellRangeAddressList(in);}\n"

In the following each data field in go is explained for each config. The data fields are the same among all splits.


field name type description
id int32 Index of the sample
