====== Excel parameter format ======

This parameter format is used by both Ecolego and the [[Parameter_database|parameter database]].

Each spreadsheet of the Excel file can contain one or more [[Parameter|parameters]] or [[Parameter_instance|instances]] respectively. The sheet contains two sections:

  - [[Parameter_definition|Definitions]] for each [[Parameter|parameter]] or [[Parameter_instance|instance]] in the spreadsheet.
  - [[Parameter_value|Values]]

===== Definition =====

The columns of the definition section are always the same:

  * **Name** - The [[Name|name]] of the parameter.
  * **Dependencies** - The dependencies [[Dependencies_(Parameter_database)|index list]] of the parameter (may be empty).
  * **Unit** - The [[Units|unit]] of the parameter.
  * **Category** - The [[category|category]] assigned to the block.
  * **Full name** - The [[Full_name|full name]] of the parameter.
  * **Symbol** - The [[Symbol|symbol]] of the parameter.
  * **Description** - A description of the parameter.

===== Values =====

The first columns of the Values section depend on the data to be presented.

  * **Parameter**
    * **Name** - The [[Name|name]] of the parameter (as listed in the definition section).
    * **Unit** - The [[Units|unit]] of the parameter (as listed in the definition section)
  * **Dependencies** - These columns are used for [[index_list#Index|indecies ]] of the [[Parameter_value|value]]. The number of columns depend on the dependencies of each parameter as listed in the definition section.
  * **Data** - This group of columns is available when the parameters have either values or time dependent data.
    * **Lookup data** - The “x” value of a lookup table, typically time.
    * **Values** - The “y” values of a lookup table
    * **Cyclic** - Whether the time series is cyclic or not (TRUE or FALSE)
    * **Interpolation** - Lookup interpolation (see [[Lookup_table|Lookup table]]) for more information.
    * **Value** - The deterministic (best estimate) value of a parameter.
  * **Distribution** - This group is displayed if any of the parameters has a distribution.
    * **Distribution** - The distribution, defined with a name and arguments.
    * **//Arguments//** - Arguments to the distributions.
  * **Statistics** - Statistical values for the parameter. In Ecolego the min/max values of a [[Parameter|parameter]] will end up here.
  * **References**
    * **References** - Literature references
    * **Comments** - Comments %%**%% Export info - See below
    * **Instance** - [[Tag|Tags]] and GUID for the parameter.

| GUID | Globally unique identifier| A 16 letter code which is used to identify a value or object in Ecolego, and which acts as a link between Ecolego, the parameter database and Excel.|


==== Export info ====

The last column of the values section is used as a link between a specific Ecolego [[Parameter|parameter]] or database [[Parameter_instance|instance]].

[[Tag|Tags]] are written in plain text, separated by comma. The GUID is added as a comment to the cell.
