F# Frame extensionsSaveCsvTRowKey, TColumnKey Method (FrameTRowKey, TColumnKey, TextWriter, FSharpOptionBoolean, FSharpOptionIEnumerableString, FSharpOptionChar, FSharpOptionCultureInfo)
Save data frame to a CSV file or a `TextWriter`. When calling the operation, you can specify whether you want to save the row keys or not (and headers for the keys) and you can also specify the separator (use `\t` for writing TSV files). When specifying file name ending with `.tsv`, the `\t` separator is used automatically. ## Parameters - `writer` - Specifies the TextWriter to which the CSV data should be written - `includeRowKeys` - When set to `true`, the row key is also written to the output file - `keyNames` - Can be used to specify the CSV headers for row key (or keys, for multi-level index) - `separator` - Specify the column separator in the file (the default is `\t` for TSV files and `,` for CSV files) - `culture` - Specify the `CultureInfo` object used for formatting numerical data [category:Input and output]
