mppair command#

Commands for working with pairs of files.

mppair subcommands are executed as part of a pipeline, where the output of one command feeds the input of the next command, similar to how a pipe on unix works.

Example#

$ mppair -n "DCDate" -i left.xlsx right.xlsx conform -i replace -r "c" -v "b" replace -r "CDR[MZ]" -v CDR --regex compare

Breaking down the command:

  1. mppair -n "DCDate" -i will drop/ignore the DCDate column

  2. left.xlsx right.xlsx is the file pair to process

  3. conform -i will conform the files to each other so that the column headers are similarly ordered

  4. replace -r "c" -v "b" takes the resulting output file pair of the preceding conform command and replaces all cells with a value of “c” to “b”

  5. replace -r "CDR[MZ]" -v CDR --regex takes the result file pair of the preceding replace command and replaces more values using a regular expression

  6. compare compares the final results

mppair compare#

This command compares two Excel files and outputs differences found, if any.

If specific sheets to compare are not specified in the options (e.g. using compare --sheet or compare --sheet-pair), then the default is to compare common sheets (i.e. sheets with the same name.) If there are no common sheets, then just compare the first sheets.

Usage#

$ mppair [OPTIONS] LEFT_FILE RIGHT_FILE compare [OPTIONS]

Options#

-s <STRING>, --sheet=<STRING>#

Name of worksheet to compare in both files. If worksheet names are different, then use the compare --sheet-pair option below.

-p <STRING>, --sheet-pair=(<STRING>,<STRING>)#

A length-2 tuple where the first and second strings are the names of the worksheets to be compared in the first and second Excel files, respectively. If the worksheet names are the same, you may use the compare --sheet option above.

-c <STRING>, --sort-col=<STRING>#

Column to sort on before comparing. Should exist in both files.

-e <STRING>, --engines=<STRING> (pandas|tablib)#

Which comparison engine to use.

  • pandas: compare using pandas DataFrames

  • tablib: compare using tablib Datasets

Arguments#

LEFT_FILE#

Required. Filename/path of the first Excel file to compare.

RIGHT_FILE#

Required. Filename/path of the other Excel file to compared with the first.

Output#

If differences are found, an Excel file is output showing the differences, one worksheet for each worksheet pair comparison.

Examples#

  1. To compare all common sheets between the two files:

    $ macpie file1.xlsx file2.xlsx compare

  2. To compare sheet CDR in left file with sheet CDR in right file:

    $ macpie --sheet CDR file1.xlsx file2.xlsx compare

  3. To compare sheet CDR_A in left file with sheet CDR_B in right file:

    $ macpie --sheet-pair CDR_A CDR_B file1.xlsx file2.xlsx compare

  4. To compare sheet CDR in left file with sheet CDR in right file, but first sorting by the InstrID column.

    $ macpie --sheet CDR --sort-col InstrID file1.xlsx file2.xlsx compare
