‘Tsv’ files are flat files that include a ‘tab delimited’ sequence of values in each line 
instead of one value per line/record.
– In most files the sequences of values are time series.
– For datasets without the dimension time (e.g. ‘area of the regions’), or that cover only 
one period of time, the sequences of values are not time series but another dimension, 
e.g. geographical series.
– The columns (or fields or cells) of the records are ‘tab delimited’.
– Time series are sorted in descending order (for explanation see the chapter ‘Hints for 
Excel users’).
– ATTENTION: cells for which there is "no data available" are NOT stored in the tsv 
files on the bulk download, doing so would explode the size of the tsv files. When using 
the on-line extraction tools like Tables, Graphs and Maps or Data Explorer, such cells 
contain the symbol ":"

– First line: header.
– Other lines: records with the sequence of values.
– First column — first line: sequence of codes separated by a comma followed by a 
code separated by a back slash ‘\’
The codes separated by a comma ‘,’ are the ‘names’ of the dimensions used for 
identifying each (time) series.
For each of these codes there is a file (with the same name plus the extension 
‘dic’) in the directory dic.
The code separated by a back slash ‘\’ is the ‘name’ of the dimension of the 
sequence of values, e.g. ‘time’ (if this is a time series) or ‘geo’ (in the case of a 
geographical series).
– First column except the first line: sequence of codes separated by a comma ‘,’ 
that represent the ‘names’ of the items (or instances or positions) of the 
dimensions. The label/title of these codes can be found in the ‘dic’ file that has 
the same name of the corresponding dimension.
– Other columns of the first line: sequence of codes corresponding to the items of 
the dimension. 
– All other columns but the first line: sequence of values.
Where available, flags are attached to values. The separator used between values 
and flags is a blank. If there are no flags, the value is followed by a blank.
– The decimal symbol used in the files is the dot ‘.’.
Note for Excel users: these files can be straightforwardly opened in Excel (see chapter 
Hints for Excel users).
