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:. In general when using the XlsxWriter module you can use A1 notation anywhere you can use row-column notation.

This also applies to methods that take a range of cells:. In Excel you can specify row or column ranges such as for all of the first row or A:A for all of the first column. In XlsxWriter these can be set by specifying the full cell range for the row or column:. This is actually how Excel stores ranges such as and A:A internally. To select the entire worksheet range you can specify A1:XFD When dealing with Excel cell references it is important to distinguish between relative and absolute cell references in Excel.

In Excel absolute references are prefixed by the dollar symbol as shown below:. See the Microsoft Office documentation for more information on relative and absolute references. The XlsxWriter utility module contains several helper functions for dealing with A1 notation as shown below. These functions can be imported as follows:. Working with Cell Notation XlsxWriter supports two forms of notation to designate the position of cells: Row-column notation and A1 notation. For example: 00 Row-column notation.

Note Ranges in A1 notation must be in uppercase, like in Excel. In Excel it is also possible to use R1C1 notation. This is not supported by XlsxWriter. Row and Column Ranges In Excel you can specify row or column ranges such as for all of the first row or A:A for all of the first column.

In XlsxWriter these can be set by specifying the full cell range for the row or column: worksheet. Relative and Absolute cell references When dealing with Excel cell references it is important to distinguish between relative and absolute cell references in Excel. In Excel absolute references are prefixed by the dollar symbol as shown below: 'A1' Column and row are relative. Cell Utility Functions 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. Parameters: row int — The cell row. Return type: A1 style string.

Parameters: col int — The cell column. Return type: Column style string. Return type: A1:B1 style range string.It can be used to write text, numbers, and formulas to multiple worksheets. Also, it supports features such as formatting, images, charts, page setup, auto filters, conditional formatting and many others. Note: Throughout XlsxWriter, rows and columns are zero indexed. The first cell in a worksheet, A1 is 0, 0B1 is 0, 1A2 is 1, 0B2 is 1, If you like GeeksforGeeks and would like to contribute, you can also write an article using contribute.

Some data we want to write to the worksheet.The first step is to apply an autofilter to a cell range in a worksheet using the autofilter method:. As usual you can also use Row-Column notation:. The autofilter defines the cell range that the filter applies to and creates drop-down selectors in the heading row.

The following is an example of how you might filter a data range to match an autofilter criteria:. The column parameter can either be a zero indexed column number or a string column name.

An expression can comprise a single statement or two statements separated by the and and or operators. For example:. Filtering of blank or non-blank data can be achieved by using a value of Blanks or NonBlanks in the expression:. The placeholder variable x in the above examples can be replaced by any simple string. The actual placeholder name is ignored internally so the following are all equivalent:. A filter condition can only be applied to a column in a range specified by the autofilter method.

For example if your column contained data for the months of the year you could filter the data based on certain months:. See Example: Applying Autofilters for a full example of all these features.

Working with Working with Autofilters An autofilter in Excel is a way of filtering a 2D range of data based on some simple criteria. Applying an autofilter The first step is to apply an autofilter to a cell range in a worksheet using the autofilter method: worksheet.

Filter data in an autofilter The autofilter defines the cell range that the filter applies to and creates drop-down selectors in the heading row. Set the autofilter. The placeholder "Region" in the filter is ignored and can be any string that adds clarity to the expression.

Images, Charts. You also cannot copy worksheets between workbooks. You cannot copy a worksheet if the workbook is open in read-only or write-only mode. Now we know how to get a worksheet, we can start modifying cells content. Cells can be accessed directly as keys of the worksheet:. This will return the cell at A4, or create one if it does not exist yet. Values can be directly assigned:.

There is also the Worksheet.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. This is a simple example but the steps involved are representative of all programs that use XlsxWriter, so let's break it down into separate parts.

By default worksheet names in the spreadsheet will be Sheet1, Sheet2 etc. Throughout XlsxWriter, rows and columns are zero indexed. The first cell in a worksheet, A1is 0, 0. In the next sections we will see how we can use the XlsxWriter module to add formatting and other Excel features.

In order to make the information clearer we would like to add some simple formatting, like this:. The differences here are that we have added Item and Cost column headers in a bold font, we have formatted the currency in the second column and we have made the Total string bold.

The main difference between this and the previous program is that we have added two Format objects that we can use to format cells in the spreadsheet. Format objects represent all of the formatting properties that can be applied to a cell in Excel such as fonts, number formatting, colors and borders. This is explained in more detail in The Format Class section. For now we will avoid getting into the details and just use a limited amount of the format functionality to add some simple formatting:.

We can then pass these formats as an optional third parameter to the worksheet. Which leads us to another new feature in this program. To add the headers in the first row of the worksheet we used write like this:. So, instead of row, col we used the Excel 'A1' style notation. It is just a little syntactic sugar to help with laying out worksheets.

Tutorial 3: W In order to make the information clearer we would like to add some simple formatting, like this: The differences here are that we have added Item and Cost column headers in a bold font, we have formatted the currency in the second column and we have made the Total string bold. To do this we can extend our program as follows: The significant changes are shown with a red line.
