ExcelCompare is a command line tool (coming soon API) to diff Excel / Open document (ods) (Open office, Libre office) spreadsheets.
It uses the Apache POI library to read Excel files. And the [OdfToolkit] (http://incubator.apache.org/odftoolkit) library to read Open document (ods) files.
This software is distributed under the MIT license.
- Identifies extra cells / sheets in addition to common cells.
- Prints all diffs & extra cells on stdout.
- Process exits with 0 if workbooks match, 1 otherwise.
- Works with xls, xlsx, xlsm, ods. You may compare any of these with each other.
- Compares only cell "contents". Formatting, macros are currently ignored.
- Using --ignore1 & --ignore2 (both optional) you may tell the diff to skip any number of sheets / rows / columns / cells.
- Other flags to control diffing (see below for description of these): --diff_numeric_precision, --diff_ignore_formulas, --diff_format.

- Requires Java 1.8 or higher.
- Assumes Java is added to PATH (to check open a cmd and run java -version)
- No other platform specific requirements
- A shell script and a bat script are packaged
Just download the zip file.
Extract it anywhere (and optionally you add the extracted folder to PATH).
Homebrew makes it easy to install ExcelCompare:
$ brew update
$ brew install excel-compare
$ excel_cmp <diff-flags> <file1> <file2> [--ignore1 <sheet-ignore-spec> ..] [--ignore2 <sheet-ignore-spec> ..]
Notes:
- --ignore1 (file1) and --ignore2 (file2) are independent of each other
- Give one and only one <sheet-ignore-spec> per sheet
- File path is assumed relative to current directory unless full path is provided
- file1 and/or file2 can be '/dev/null' or '\.\NUL' (on windows) which is treated as empty file. This is useful for using ExcelCompare for git diff.
- --diff_numeric_precision: by default numbers are diffed with double precision, to change that specify this flag as --diff_numeric_precision=0.0001
- --diff_ignore_formulas: by default for cells with formula, formula is compared instead of the evaluated value. Use this flag to compare evaluated value instead
- --diff_format: by default output is in 'excel_cmp' format, use --diff_format=unified to output in Unified Diff format instead
<sheet-name>:<row-ignore-spec>:<column-ignore-spec>:<cell-ignore-spec>
- Leaving <sheet-name> blank corresponds to this spec applying to all sheets, for example ::A will ignore column A in all sheets
- To ignore whole sheet, just provide <sheet-name>
- Any cell satisfying any ignore spec in the sheet (row, col, or cell) will be ignored in diff
- You may provide only <cell-ignore-spec> as - <sheet-name>:::<cell-ignore-spec>
<comma sep list of row or row-range>
- Row numbers begin from 1
- Range of rows may be provide as: 1-10
- Rows and ranges may be mixed as: 1-10,12,20-30 etc.
<comma sep list of column or column-range>
- Similar to Row Ignore Spec
- Columns are letters starting with A
<comma sep list of cell or cell-range>
- Similar to Row Ignore Spec
- Cells are in usual Excel notation A1 D10
- Range may be provided as A1-D10

Each diff or extra cell is reported per line as follows
DIFF Cell at <Cell> => <Value1> v/s <Value2> EXTRA Cell in <WB> <Cell> => <Value> -
Then a summary
----------------- DIFF ------------------- Sheets: [<Set of sheets with diffs>] Rows: [<Set of rows with diffs>] Cols: [<Set of columns with diffs>] ----------------- EXTRA WB1 ------------------- Sheets: [<Set of extra sheets in WB1>] Rows: [<Set of extra rows in WB1>] Cols: [<Set of extra columns in WB1>] ----------------- EXTRA WB2 ------------------- Sheets: [<Set of extra sheets in WB2>] Rows: [<Set of extra rows in WB2>] Cols: [<Set of extra columns in WB2>] ----------------------------------------- -

Excel files xxx.xlsx and yyy.xlsx match
- Diffs are reported in the "unified diff" style, with no surrounding context (i.e., a la
diff -U0). - Each sheet containing a diff or an extra cell begins with a header as follows: --! ++!
- Each row containing a diff or an extra cell begins with a line that identifies a contiguous series of cells in the row as follows: @@ , , @@
- Each diff or extra cell is reported as follows: - -... - + +... +
- If there are multiple series of diff or extra cells, the row header and cell data will be repeated, with the column numbers idetifying the start and end of each series.
- There is no summary, and if there are no diffs and no extra cells, the output is empty.
