XlsxWriter supports two forms of notation to designate the position of cells: Row-column notation and A1 notation.
Row-column notation uses a zero based index for both row and column while A1 notation uses the standard Excel alphanumeric sequence of column letter and 1-based row. For example:
(0, 0) # Row-column notation.
('A1') # The same cell in A1 notation.
(6, 2) # Row-column notation.
('C7') # The same cell in A1 notation.
Row-column notation is useful if you are referring to cells programmatically:
for row in range(0, 5):
worksheet.write(row, 0, 'Hello')
A1 notation is useful for setting up a worksheet manually and for working with formulas:
worksheet.write('H1', 200)
worksheet.write('H2', '=H1+1')
In general when using the XlsxWriter module you can use A1 notation anywhere you can use row-column notation.
XlsxWriter supports Excels worksheet limits of 1,048,576 rows by 16,384 columns.
Note
Ranges in A1 notation must be in uppercase, like in Excel.
Note
In Excel it is also possible to use R1C1 notation. This is not supported by XlsxWriter.
When dealing with Excel cell references it is important to distinguish between relative and absolute cell references in Excel.
Relative cell references change when they are copied while Absolute references maintain fixed row and/or column references. In Excel absolute references are prefixed by the dollar symbol as shown below:
A1 # Column and row are relative.
$A1 # Column is absolute and row is relative.
A$1 # Column is relative and row is absolute.
$A$1 # Column and row are absolute.
See the Microsoft Office documentation for more information on relative and absolute references.
Some functions such as conditional_format()
require absolute
references.
It is also possible to define and use “Defined names/Named ranges” in
workbooks and worksheets, see define_name()
:
workbook.define_name('Exchange_rate', '=0.96')
worksheet.write('B3', '=B2*Exchange_rate')
See also Example: Defined names/Named ranges.
The XlsxWriter
utility
module contains several helper functions for
dealing with A1 notation as shown below. These functions can be imported as
follows:
from xlsxwriter.utility import xl_rowcol_to_cell
cell = xl_rowcol_to_cell(1, 2) # C2
xl_rowcol_to_cell
(row, col[, row_abs, col_abs])Convert a zero indexed row and column cell reference to a A1 style string.
Parameters: | |
---|---|
Return type: | A1 style string. |
The xl_rowcol_to_cell()
function converts a zero indexed row and column
cell values to an A1
style string:
cell = xl_rowcol_to_cell(0, 0) # A1
cell = xl_rowcol_to_cell(0, 1) # B1
cell = xl_rowcol_to_cell(1, 0) # A2
The optional parameters row_abs
and col_abs
can be used to indicate
that the row or column is absolute:
str = xl_rowcol_to_cell(0, 0, col_abs=True) # $A1
str = xl_rowcol_to_cell(0, 0, row_abs=True) # A$1
str = xl_rowcol_to_cell(0, 0, row_abs=True, col_abs=True) # $A$1
xl_cell_to_rowcol
(cell_str)Convert a cell reference in A1 notation to a zero indexed row and column.
Parameters: | cell_str (string) – A1 style string, absolute or relative. |
---|---|
Return type: | Tuple of ints for (row, col). |
The xl_cell_to_rowcol()
function converts an Excel cell reference in A1
notation to a zero based row and column. The function will also handle Excel’s
absolute, $
, cell notation:
(row, col) = xl_cell_to_rowcol('A1') # (0, 0)
(row, col) = xl_cell_to_rowcol('B1') # (0, 1)
(row, col) = xl_cell_to_rowcol('C2') # (1, 2)
(row, col) = xl_cell_to_rowcol('$C2') # (1, 2)
(row, col) = xl_cell_to_rowcol('C$2') # (1, 2)
(row, col) = xl_cell_to_rowcol('$C$2') # (1, 2)
xl_col_to_name
(col[, col_abs])Convert a zero indexed column cell reference to a string.
Parameters: | |
---|---|
Return type: | Column style string. |
The xl_col_to_name()
converts a zero based column reference to a string:
column = xl_col_to_name(0) # A
column = xl_col_to_name(1) # B
column = xl_col_to_name(702) # AAA
The optional parameter col_abs
can be used to indicate if the column is
absolute:
column = xl_col_to_name(0, False) # A
column = xl_col_to_name(0, True) # $A
column = xl_col_to_name(1, True) # $B
xl_range
(first_row, first_col, last_row, last_col)Converts zero indexed row and column cell references to a A1:B1 range string.
Parameters: | |
---|---|
Return type: | A1:B1 style range string. |
The xl_range()
function converts zero based row and column cell references
to an A1:B1
style range string:
cell_range = xl_range(0, 0, 9, 0) # A1:A10
cell_range = xl_range(1, 2, 8, 2) # C2:C9
cell_range = xl_range(0, 0, 3, 4) # A1:E4
xl_range_abs
(first_row, first_col, last_row, last_col)Converts zero indexed row and column cell references to a $A$1:$B$1 absolute range string.
Parameters: | |
---|---|
Return type: | $A$1:$B$1 style range string. |
The xl_range_abs()
function converts zero based row and column cell
references to an absolute $A$1:$B$1
style range string:
cell_range = xl_range_abs(0, 0, 9, 0) # $A$1:$A$10
cell_range = xl_range_abs(1, 2, 8, 2) # $C$2:$C$9
cell_range = xl_range_abs(0, 0, 3, 4) # $A$1:$E$4
