Read xls and xlsx files. Readexcel calls excelformat to determine if path is xls or xlsx, based on the file extension and the file itself, in that order. Use readxls and readxlsx directly if you know better and want to prevent such guessing. SysTools XLSX Viewer Tool is the best rated free Excel file reader software to open, & view damaged, corrupt XLSX files. With XLSX file opener, users can view all kinds of Excel Spreadsheet files:“Protected,” “Marked as Final,” and “Strict Open XML (XLSX) created by Excel, MS Office (Excel 2019, 2016, 2013, 2010, and 2007), Libre Spreadsheet, G Suite Spreadsheet, Office 365 Excel. XLS Reader is a simple freeware for viewing spreadsheet documents created by Microsoft Excel, a completely free Excel file viewer. Read Excel with Python Pandas. Read Excel files (extensions.xlsx,.xls) with Python Pandas. To read an excel file as a DataFrame, use the pandas readexcel method. You can read the first sheet, specific sheets, multiple sheets or all sheets. Pandas converts this to the DataFrame structure, which is a tabular like structure.
Opens XLSX workbook and reads its worksheets.
Example
Sheet contents
Sheets are loaded on-demand by sheet/3
and sheets/2
.
The sheet contents is returned as a list of lists:
The behavior of the sheet parser can be customized for eachindividual sheet, see sheet/3
.
Cell types
This library takes a best effort approach for determining cell types.In order of priority, the actual type of an XLSX cell value is determined using:
- basic cell properties (e.g. boolean)
- predefined known styles (e.g. default money/date formats)
- introspection of the custom format string associated with the cell
Custom formats supported by default
- percentages
- ISO 8601 date/time (y-m-d)
- US date/time (m/d/y)
- European date/time (d/m/y)
Additional custom formats support
If the spreadsheet you need to process contains some unusual cell formatting, youmay provide hints to map format strings to a known cell type.
The hints are given as a list of {matcher, type}
tuples. The matcher is either astring or regex to match against the custom format string. The supported types are:
:string
:number
:percentage
:date
:time
:date_time
:unsupported
(used for explicitly unsupported styles and formats)
Example
To find out what custom formats are in use in the workbook, you can inspect package.workbook.custom_formats
:

Xlsx Reader Online
When processing files with multiple sheets, async_sheets/3
is ~3x faster than sheets/2
but it comes with a caveat. async_sheets/3
uses Task.async_stream/3
under the hood and thusruns each concurrent task with a timeout. If you expect your dataset to be of a significant size,you may want to increase it from the default 10000ms (see 'Concurrency options' below).
If the order in which the sheets are returned is not relevant for your application, you canpass ordered: false
(see 'Concurrency options' below) for a modest speed gain.

)skip_row?
: function callback that determines if a row should be skipped. Takes precedence overblank_value

The Decimal
type requires the decimal library.
Examples
Skipping rows
When using the skip_row?
callback, rows are ignored in the parser which is more memory efficient.

Sheets can filtered by name using:
- a string (e.g.
'Exact Match'

~r/Sheet +/
) - a list of string and/or regexes (e.g.
['Parameters', ~r/Sheet [12]/]

C++ and .NET Framework This tutorial is valid for C++ applications that cannot use .NET Framework. It is recommended, for better performances, that if the C++ application already uses or can use .NET Framework to make use of this similar code sample. Overloaded methods For methods with same name but different parameters, only the first method overload retains the original name. Subsequent overloads are uniquely renamed by appending to the method name '_2', '_3', etc (method, method_2, method_3), an integer that corresponds to the order of declaration that can be found in EasyXLS.h, a file that comes with EasyXLS installation. | ||
