WARNING Always work on copies of your data files with these programs and keep copies of the originals safe. They have had the bare minimum of testing and we would not want to damage many hours of painstaking work.
If you come across a bug/problem/invalid output related to the program, I will need a copy of the data file that failed and the error listing to diagnose what went wrong.
I reserve the right to fix errors by changing the documentation.
See revision log for current version and bug fixes.
csv2dat
has two primary functions. The first is
to generate an IN-CENS data file from the SS-CENS spreadsheet
data entry file. It does a lot of checking of the contents of the
fields to pick up errors in
data entry. Many of these are correctable later by CHECK-CENS
(WINCC) but some may be better corrected in the spreadsheet form
before passing on. This is the mode used by CSVCHECK where the
data output file is discarded.
For Spreadsheet data entry (SS-CENS mode), a sample blank
datasheet is enclosed in the ZIP file. This is provided in
.XLS
format for all versions of Excel from 5.0
upwards, assorted MS Works versions and in .CSV
format for most spreadsheet programs. Take a copy and rename it
to be the same as the piece number (e.g.
RGxxnnnn.XLS
) before you start. The format of the
spreadsheed is implicitly documented on the message list page but the column headings
should be self explanatory.
The second primary function of csv2dat
is to
convert a file back to the FreeCEN format after having been
repaired by dat2csv
and corrected using a
spreadsheet program. It is designed to produce a valid IN-CENS
data file regardless of Warnings in the
.CSV
file but Errors should be
taken seriously. The message
list says what action has been taken automatically. It
not only checks the contents of the individual fields for valid
data, but also looks for errors in the relationship from one
record to another (such as schedule and page sequence).
For running csv2dat
via a menu, see FC-TOOLBOX.
For running csv2dat
via a CSVCHECK, see the
CSVCHECK Home
Page.
Create a folder on your disk (we suggest
\fctools
). Put the program csv2dat.exe
into this folder. Export, copy or save your spreadsheet data file
into this folder in .CSV
(Comma Separated Values)
format (e.g. rgxxnnnn.csv
). An additional file,
CHAP1891.TXT
, should
be present in the same folder as the program. This 1891 file is
used for all years 1851–91. It provides data for the
County Code check. If the required file is missing, this check is
bypassed with only a warning.
Run the program by double clicking on it
A black console window (DOS) will open which says
Enter command :
This is a prompt for a command line which must contain the file name.
Year ENG/WLS SCT 1841 ho41nnnn.csv hs4zzmmm.csv 1851 ho51nnnn.csv hs5zzmmm.csv 1861 rg09nnnn.csv rs6zzmmm.csv 1871 rg10nnnn.csv rs7zzmmm.csv 1881 rg11nnnn.csv rs8zzmmm.csv 1891 rg12nnnn.csv rs9zzmmm.csv 1901 rg13nnnn.csv rs0zzmmm.csv
Some pieces are rather large—to allow these to be divided to delegate the work, the following is possible.
.VLD
files) can be uploaded to the online
database in this form.ho1xxnnn.csv
where xx = pre-defined
values. This format is no longer supported.ho4ynnnn.csv
&
ho5ynnnn.csv
where y = a letter
“a–z” meaning parts 1 to 26 respectively.
These (.VLD
files) MUST NOT be uploaded to the
online database in this form. Only full pieces are
acceptable.Unpadded numbers (without leading zeros) will be accepted but are converted to the correct form for output files.
It works out the year and piece number from the file name (so don't change them!)
When you hit enter the program will run. There is a scrolling count so you can see how it is getting along, but it is very quick on modern machines.
The program does a lot of sanity checks to ensure that the output data file is valid.
When it finishes it will say how many records have been output, how many households and say
<hit return to exit>...
When you do so, the window will close.
Now look in the messages file (*.erc
). Here it
will give some information about the run and again say how many
records have been output and how many households and also any
other problems detected. Check this file carefully before
accepting the database. Keep this file with the output file, it
will be useful later for correcting the data if necessary.
The types of messages are “Fatal” which stop the program immediately and do not produce an output file; “Error” which may produce an invalid output file; and “Warning” which will attempt to correct the error and produce a valid output file. See also “Info” messages switched on with the -v VERBOSE switch.
If any “Error” messages are seen (and “Fatal” of course) I would suggest that you try to correct the data file and run the program again. “Warning”s may or may not need fixing and this can be done on the input data, or afterwards by other means such as WINCC or VALDREV.
Note that one message can sometimes generate other spurious
ones. A lot of things that are warnings in dat2csv
are errors in csv2dat
and vice-versa because they
are concentrating on different problems.
These extra instructions are for advanced use of the program, not for novices.
The file name can be a full path specification i.e.
D:\folder\rg129876.csv
. The output and message files
will be put in the same path.
The default mode assumes a SS-CENS brief (skeleton) style
.CSV
input file. A selection of messages (Error and
Warning) are given relating to problems with the file, if
any.
There are alternatives available by using a switch before the file name e.g.
-c rgxxnnnn.csv
The switches are
dat2csv
. See reference section for a detailed
description of this format..CSV
file containing checked data. The file
created has extension .VAL
for historical reasons.
This may need to be changed to .CHE
(for checked)
to be accepted by other software..CSV
file containing validated data. The file
created has extension .VLD
(for validated).Use (-a and -c) or (-a and -d) together to achieve both effects at the same time.
These switches (above) are mutually exclusive and cannot be combined.
These switches (above) are not available via the FC-TOOLBOX menu.
The command can also be run from a DOS (Command) console from the start by following the command name with the options and file name. e.g.
D:\fctools>csv2dat -v -c rg129876.csv
DOS style / switches can be used if prefered but they are always placed before the file name.
Finally, the program can also be invoked by drag-and-drop of a data file onto the program or a shortcut, e.g. on the desktop [if this feature still works on your PC; it has died on mine :( ]. No opportunity is given to enter switches but it is a very quick way to make default runs. The output and message files are sent to the same folder as the source.
The return code from csv2dat
is 12 if any Fatal
errors occured, 8 if any Errors occured, 4 if any Warnings
occured and zero otherwise.
WARNING: This program CANNOT tell the file type from the data, the correct parameter must be used if it is not the default.
Further WARNINGS The cycle
dat2csv
followed by csv2dat
does not
always produce an identical file to the original, even if there
are no errors or warnings. This can have some
“interesting” side effects.
dat2csv
changes the relative record
numbers making it hard to correlate the data with other files
that use the record numbers.csv2dat
when in
BRIEF mode. This can make it harder to correlate information
such as the CHECK-CENS (WINCC) .TXT
file with the
data. This is not generally a serious problem but, if
necessary, ALL mode preserves these reference numbers.
