SpreadSheetDiff

A tool to compare two Excel or OpenOffice files (.xlsx or .ods format) with annotation of the differences. The files to be compared must have the same basic structure. That means the labels and the number of their sheets must be the same in both files.

Compare two Excel/OpenOffice files:

Input files:

As input .xlsx or .ods files are accepted.

Output files:

The differences are stored in the cells of an .xlsx results file. A difference is marked in corresponding cell with >>> annotation between the different values: [value of first input file] >>> [value of second input file]

In addition, they are stored with the corresponding cell localization (sheet name, row and column) in a SpreadSheetDiff_annotations file in .txt format:

Help:

spreadsheetdiff -h

Help output:

usage: spreadsheetdiff [-h] -i INPUT_FILES INPUT_FILES -o OUT_DIR [-b] [-c BG_COLOR] [-v] [-q]

A tool to compare two excel files with annotation of the differences.

optional arguments:
  -h, --help            show this help message and exit
  -i INPUT_FILES INPUT_FILES, --input-files INPUT_FILES INPUT_FILES
                        Two paths to the Excel files (.xlsx or .ods format) to be compared with each other.
  -o OUT_DIR, --out-dir OUT_DIR
                        Path to the output directory.
  -b, --bold            Displays differences in resulting spreadsheet in bold text style.
  -c BG_COLOR, --bg-color BG_COLOR
                        Displays differences in resulting spreadsheet in a specific color. The color has to be given in quoted hex color code (e.g.
                        '#ff0000') or color name (e.g. red).
  -v, --verbose         Increase output verbosity to debug level.
  -q, --quiet           Decrease output verbosity to warning level. Ignores -v flag.

Examples package execution:

spreadsheetdiff -v -c '#ff0000' -b -i ../test_table_1.ods ../test_table_3.xlsx -o ../diff

spreadsheetdiff -q -c 'yellow' -i ../test_table_3.xlsx ../test_table_4.xlsx -o ../diff

Example output:

Example for local execution of the main method:

python3 spreadsheetdiff/main.py -v -i ../file_3.xlsx ../file_2.ods -o ../diff

Example of module import:

from spreadsheetdiff import main as ssd

style = [("bold", True), ("bg_color", "#ff0000")]
ssd.compare_excel_files('../file_1.ods', '../file_2.ods', '../diff', style)

style = [("bg_color", "yellow")]
ssd.compare_excel_files('../file_1.ods', '../file_3.xlsx', '../diff', style)

Uninstall package:

pip3 uninstall spreadsheetdiff
