 ==== Description
 
-Reads a csv line and constructs a record with literals.
-The record id represents the row number and the literal names represent the column numbers.
-The literal value holds the column content.
-
-NOTE: The enumeration starts with 1.
-
-==== Syntax
-
-```
-decode-literal-csv([separator])
-```
-
-==== Parameters
+A simple encoder that constructs a table of __Comma-separated values__ (CSV).
 
-* `separator`: Delimiter symbol (Default: comma).
+Structure:

-=== encode-literal-csv
-
-==== Description
+* Each record represents a row
+** The sequential order of literal _values_ forms a *row*
+** The sequential order of literal _names_ of the first record is used as _header_ (Optional)
+* Each value in a row is surrounded by quotation marks (Quote Character:__"__)
 
-Encodes each record as a csv line.
-Each row contains all literal values that exist in a record.
+NOTE: If a sequence of literals (2 or more) share the same name,
+the values of those literals will be collected in the corresponding row.
+The column will contain a inner row (a nested csv row).
 
 ==== Syntax
 
 ```
-encoder-literal-csv([separator],[includeRecordId])
+encode-csv([separator],[includeHeader],[includeRecordId])
 ```
 
 ==== Parameters
 
 * `separator`: Delimiter symbol (Default: comma)
-* `includeRecordId`: Add the record id as first element of each line (Default: false).
+* `includeHeader`: Add a header with column names (Default: false).
+* `includeRecordId`: Add the record id as first element of each row (Default: false).
 
 ==== Example
 
 Flux:
 
 ```
-... | encoder-literal-csv(separator=",", includeRecordId="true") | print;
+... | encoder-csv(separator=",", includeRecordId="true") | print;
