# delimited2fixedwidth Convert files from delimited (e.g. CSV) to fixed width format [](https://github.com/e2jk/delimited2fixedwidth/releases/latest) [](https://pypi.org/project/delimited2fixedwidth/) [](https://travis-ci.com/e2jk/delimited2fixedwidth) [](https://codecov.io/gh/e2jk/delimited2fixedwidth) [](https://github.com/e2jk/delimited2fixedwidth/commits/master) [](../../tree/master/LICENSE) How to run the program ====================== How to install the program -------------------------- For Linux and Windows, download the latest version from [here](https://github.com/e2jk/delimited2fixedwidth/releases/latest) (look under the "Assets" section) and run it on your system, no need to install anything else. The program can also be installed from the Python Package Index: ``` pip install delimited2fixedwidth ``` See below [how to install from source](#how-to-install-from-source). Configuration file ------------------ In order for the program to know how to transform your delimited file into a fixed-width file, you will need to provide a configuration file describing the length and type of values expected for your output file. An example configuration file can be found at [`tests/sample_files/configuration1.xlsx`](../../tree/master/tests/sample_files/configuration1.xlsx) A configuration file is a simple Excel `.xlsx` file in which each row represents a single field expected in the output file (the fixed-width file), and at least these 3 column headers, i.e. the first line in your Excel file: * Length * Output format * Skip field The **Length** value is self-explanatory: it represents how long the field will be in the generated fixed-width file. If the value in the input file is shorter than this defined length, it will be padded with `0`s or spaces, depending on the type of Output format (see next section). The **Output format** defines how the input value must be treated and transformed. The following values are supported: * `Integer` * A numeric value that gets padded with `0`s added to the left * Example: "`123`" becomes "`000123`" if a length of 6 is defined * `Decimal` * Decimal numbers get sent as "cents" instead of "dollars", rounded to the nearest cent. (yeah, weird explanation -- better have a look at the example...). Also padded with `0`s added to the left. * Example: "`123.458`" becomes "`00012346`" if a length of 8 is defined * `Keep numeric` * strips all non-numeric characters from an input value and treats the remaining value as `Integer` * Example: "`1-2.3a`" becomes "`000123`" if a length of 6 is defined * Date * A date to be converted from one format to another. The input value can be sent with either Day or Month as first element or as ISO format YYYYMMDD, and with a slash, dash, dot or no separator. When there is a separator defined, the day and month can omit the leading 0, if need be. See at the top of the [`test_main.py` file](https://github.com/e2jk/delimited2fixedwidth/blob/master/tests/test_main.py#L37) for the full list of supported codes. * Examples: * "`21/06/2020`" becomes "`20200621`" with a format of `Date (DD/MM/YYYY to YYYYMMDD)` and a length of 8 * "`6-21-2020`" becomes "`20200621`" with a format of `Date (MM-DD-YYYY to YYYYMMDD)` and a length of 8 * "`21062020`" becomes "`20200621`" with a format of `Date (DDMMYYYY to YYYYMMDD)` and a length of 8 * "`6.21.2020`" becomes "`21/06/2020`" with a format of `Date (MM.DD.YYYY to DD/MM/YYYY)` and a length of 10 * `Time` * A time sent as hour:minutes (with or without colon in the input data) will be sent out without the colon * Example: "`20:06`" becomes "`2006`" if a length of 4 is defined * `Text` * The value gets sent without format changes (such as those outlined above for date and time), with spaces added at the end, on the right of the string * Example: "`Hello`" becomes "<code>Hello&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</code>" if a length of 10 is defined Finally, setting the value of the **Skip field** column to "`True`" allows to send a field as blank in the output file, respecting the field size and padding type: `0`s or spaces depending on the defined output format. Running the program ------------------- Open a Command Line window `cmd` and indicate your input file name, output file name and configuration file to use. You can additionally indicate if your input file uses a specific field separator (default is `,`), textual field wrapper (default is `"`), or if you want to skip a specific number of header or footer files from your input file. See the [Program help information](#program-help-information) section below for details on how to populate these arguments. An example run of the program could look like this: ``` delimited2fixedwidth.exe --input data\input_file.txt --config data\configuration_file.xlsx --output data\output_file.txt --delimiter "^" --skip-header 1 --skip-footer 1 ``` Program help information ------------------------ ``` usage: delimited2fixedwidth.py [-h] [--version] -o OUTPUT [-x] -i INPUT -c CONFIG [-dl DELIMITER] [-q QUOTECHAR] [-sh SKIP_HEADER] [-sf SKIP_FOOTER] [-l LOCALE] [-t TRUNCATE] [-dv DIVERT] [-d] [-v] Convert files from delimited (e.g. CSV) to fixed width format optional arguments: -h, --help show this help message and exit --version show program's version number and exit -o OUTPUT, --output OUTPUT Specify the output file -x, --overwrite-file Allow to overwrite the output file -i INPUT, --input INPUT Specify the input file -c CONFIG, --config CONFIG Specify the configuration file -dl DELIMITER, --delimiter DELIMITER The field delimiter used in the input file (default ,) -q QUOTECHAR, --quotechar QUOTECHAR The character used to wrap textual fields in the input file (default ") -sh SKIP_HEADER, --skip-header SKIP_HEADER The number of header lines to skip (default 0) -sf SKIP_FOOTER, --skip-footer SKIP_FOOTER The number of footer lines to skip (default 0) -l LOCALE, --locale LOCALE Change the locale, useful to handle decimal separators -t TRUNCATE, --truncate TRUNCATE Comma-delimited list of field numbers for which the output will be truncated at the maximum line length, should the input value be longer than the maximum defined field length. If not set, a field that is too long will cause the script to stop with an error. -dv DIVERT, --divert DIVERT Diverts to a separate file the content from rows containing a specific value at a specific place. The format of this parameter is "<field number>,<value to divert on>" (without quotes). This parameter can be repeated several times to support different values or different fields. The diverted content will be saved to a file whose name will be the output filename with "_diverted" added before the file extension. -d, --debug Print lots of debugging statements -v, --verbose Be verbose ``` Development information ================
