+# Excel Format Plugin
+This plugin enables Drill to read Microsoft Excel files. This format is best
used with Excel files that do not have extensive formatting, however it will
work with formatted files, by allowing you to define a region within the file
where the data is.
+
+The plugin will automatically evaluate cells which contain formulae.
+
+## Plugin Configuration
+This plugin has several configuration variables which must be set in order to
read Excel files effectively. Since Excel files often contain other elements
besides data, you can use the configuration variables to define a region within
your spreadsheet in which Drill should extract data. This is potentially
useful if your spreadsheet contains a lot of formatting or other complications.
+
+* `headerRow`: Set to -1 if there are no column headers.
+* `lastRow`: This defines the last row of your data. The default is an
arbitrary large number. You only will need to set this if you want Drill to
stop reading at a specific location.
+* `sheetName`: This is the name of the sheet you want to query. This will
default to the first sheet in the file if left undefined.
+* `firstColumn`: If you want to define a region within a spreadsheet, this is
the left-most column index. This is indexed from one. If set to `0` Drill
will start at the left most column.
+* `lastColumn`: If you want to define a region within a spreadsheet, this is
the right-most column index. This is indexed from one. If set to `0` Drill
will read all available columns. This is not inclusive, so if you ask for
columns 2-5 you will get columns 2,3 and 4.
+
+## Usage
+You can specify the configuration at runtime via the `table()` method or in
the storage plugin configuration. For instance, if you just want to query an
Excel file, you could execute the query as follows:
+
+```
+SELECT <fields>
+FROM dfs.`somefile.xlsx`
+```
+
+If you wanted to query a different sheet other than the default, use the
`table()` method as shown below:
