# write_csv

The `write_csv` function writes a document’s metadata and content to a comma-separated values (CSV) file on disk. The function writes a blank line, followed by a line of field names, followed by a line that contains the field values.

The `CsvWriterFieldNames` argument specifies the document fields that you want to write to the CSV file:

- The `DREREFERENCE` and `DRECONTENT` fields are always included. You do not need to specify these fields.
- To specify a field, type the field name. For example: For example: `"MyField"`.
- To specify a sub-field, type the field name, followed by a forward slash, followed by the name of the sub-field. For example: `"MyField/SubField"`.
- To specify a field attribute, type the field name, followed by a forward slash, followed by the name of the attribute. Prefix the attribute name with the '`@`' character. For example: `"MyField/@attribute"`.
- If you specify a field that has multiple values, all of the values are included in the output.

## Syntax

    write_csv( doc, CsvWriterFilename , CsvWriterFieldNames
           [, CsvWriterArchiveDirectory, CsvWriterMaxSizeKBs] )

## Arguments

Argument | Description
--- | ---
`doc` | (LuaDocument) The document to write to the CSV file.
`CsvWriterFilename` | (string) The filename of the output CSV file.
`CsvWriterFieldNames` | (table of strings) The document fields that you want to write to the CSV file. The function always writes the document’s reference (`DREREFERENCE`) and content (`DRECONTENT`), so you do not need to specify these fields.
`CsvWriterArchiveDirectory` | (string) The path to the directory where CSV files are archived when they exceed the size specified by `CsvWriterMaxSizeKBs`.
`CsvWriterMaxSizeKBs` | (integer) The maximum size of CSV files, in kilobytes. When a file exceeds this size it is moved to the archive directory specified by `CsvWriterArchiveDirectory`. A timestamp is added to the file name so that it has a unique name.

## Returns

Boolean. Returns `true` if the CSV file was created successfully, and `false` otherwise.

## Example

    function handler(document)
       write_csv(document, "MyTask.csv",
           {"MyField", "MyField/Subfield","MyField/@attribute" } ,
           "CSVarchive", 1024 )
       return true
    end
