A sample unloading is a sequence of rows in UTF-8 encoding. The rows should be separated by CRLF or LF characters. Cell values in the row should be separated by TAB or ‘,’ (comma) characters. These limitations follow TSV (Tab separated values) CSV (Comma separated values) format. The number of cells in all rows must be the same. When you create an unloading, the number of cells must be specified. It is equal to the number of column names, which are passed to the Create function. It is only possible to upload contents to an existing sample unloading if the number of cells is equal to the number specified during the unloading creation. If a different number of cells is specified it will make the unloading invalid.
A sample document is a file of any format. If the file is not an encrypted archive, the System extracts the files from the archive, process them with separately from each other and creates a separate sample document basing on each extracted file (a sample document cannot be created based on the whole archive). All created sample documents are placed into the catalog, selected while creating a sample document. If the file is an encrypted archive, sample document cannot be created by System. If the file is an envelope, System will create one sample document basing on the file.
