Spreadsheet and CSV input.

Cove allows XLSX and CSV import in all the standards it supports. It uses the flattentool library to do the conversion from these formats to either XML or JSON. Please look at flattentool documentation for detailed information on how to create spreadsheet templates for a particular standard.


Cove configures flattentool to allow an extra sheet in your spreadsheets (not for CSV) named "Meta" (case sensitive). This sheet contains items at the top level of your document. For JSON this means key/value pairs that appear at the top level object and in XML attributes on the outermost tag.

The "Meta" sheet is expected to be vertically aligned, so headings are on first column (not first row), and values are on second column. So a sheet named Meta could look like:

dataLicense CC
version 2
publishedDate 2001-01-01

This will create a JSON object like:

{"dataLicense": "CC",
 "version: "2",
 "publishedDate": "2001-01-01",
 "someNestedData: [...]}

For XML like:

<toptag dataLicense="CC" version="2" publishedData="2001-01-01">

Hash command line at top of file.

For both CSV and Spreadsheet (XLSX) flattentool allows a special line at the top of the file. This line has to start with a "#" character in the first cell (i.e A1 in a spreadsheet) and nothing else. The rest of line contains commands to customize how the spreadsheet is parsed. For example:

# skipRows 1 headerRows 2
this line is ignored
Some Headings Here
Some More Headings Here
some data here


If there exists a hash command line at the top of the metatab sheet this will apply default commands across all other sheets (not the metatab itself). This can be overridden by supplying a hash commend line for a particular sheet.

The commands that flattentool (and therefore cove) allows are the following:


This is followed by a number i.e skipRows 3 and says how many rows at the top of the file (ignoring the hash line) will be ignored. For example:

# skipRows 1  
this line is ignored
Some Headings Here
some data here

Defaults to 0 rows skipped.


This is followed by a number i.e headerRows 2 and says how many rows are header lines in the file. All header rows apart from the first one will be ignored. For example:

# headerRows 2  
Some Headings Here
More headings here
some data here

Defaults to 1 header rows. 0 rows is invalid as cove needs a heading row.


This says that this whole sheet should not be looked at by cove:

# ignore  
Everthing ignored on
this sheet  


This says that columns can be commented out by placing a # before the column name. If this command is used in the metatab it means that sheet names can be ignored by adding a # before the sheet name:

# hashcomments  
Heading # Ignored Heading 2
some ignored data data
