Usage

As a standalone library

Write to an xls file

Here’s the sample code to write a dictionary to an xls file:

>>> from pyexcel_xls import XLWriter
>>> data = OrderedDict() # from collections import OrderedDict
>>> data.update({"Sheet 1": [[1, 2, 3], [4, 5, 6]]})
>>> data.update({"Sheet 2": [["row 1", "row 2", "row 3"]]})
>>> writer = XLWriter("your_file.xls")
>>> writer.write(data)
>>> writer.close()

Read from an xls file

Here’s the sample code:

>>> from pyexcel_xls import XLBook

>>> book = XLBook("your_file.xls")
>>> # book.sheets() returns a dictionary of all sheet content
>>> #   the keys represents sheet names
>>> #   the values are two dimensional array
    >>> import json
>>> print(json.dumps(book.sheets()))
{"Sheet 1": [[1.0, 2.0, 3.0], [4.0, 5.0, 6.0]], "Sheet 2": [["row 1", "row 2", "row 3"]]}

Write an xls to memory

Here’s the sample code to write a dictionary to an xls file:

>>> from pyexcel_xls import XLWriter
>>> data = OrderedDict()
>>> data.update({"Sheet 1": [[1, 2, 3], [4, 5, 6]]})
>>> data.update({"Sheet 2": [[7, 8, 9], [10, 11, 12]]})
>>> io = StringIO()
>>> writer = XLWriter(io)
>>> writer.write(data)
>>> writer.close()
>>> # do something witht the io
>>> # In reality, you might give it to your http response
>>> # object for downloading

Read from an xls from memory

Continue from previous example:

>>> # This is just an illustration
>>> # In reality, you might deal with xls file upload
>>> # where you will read from requests.FILES['YOUR_XL_FILE']
>>> book = XLBook(None, io.getvalue())
>>> print(json.dumps(book.sheets()))
{"Sheet 1": [[1.0, 2.0, 3.0], [4.0, 5.0, 6.0]], "Sheet 2": [[7.0, 8.0, 9.0], [10.0, 11.0, 12.0]]}

As a pyexcel plugin

Import it in your file to enable this plugin:

from pyexcel.ext import xls

Please note only pyexcel version 0.0.4+ support this.

Reading from an xls file

Here is the sample code:

>>> import pyexcel as pe
>>> from pyexcel.ext import xls

# "example.xls"
>>> sheet = pe.load_book("your_file.xls")
>>> sheet
Sheet Name: Sheet 1
+---+---+---+
| 1 | 2 | 3 |
+---+---+---+
| 4 | 5 | 6 |
+---+---+---+
Sheet Name: Sheet 2
+-------+-------+-------+
| row 1 | row 2 | row 3 |
+-------+-------+-------+

Writing to an xls file

Here is the sample code:

>>> sheet.save_as("another_file.xls")

Reading from a IO instance

You got to wrap the binary content with stream to get xls working:

>>> # This is just an illustration
>>> # In reality, you might deal with xls file upload
>>> # where you will read from requests.FILES['YOUR_XL_FILE']
>>> xlfile = "another_file.xls"
>>> with open(xlfile, "rb") as f:
...     content = f.read()
...     r = pe.load_book_from_memory("xls", content)
...     print(r)
...
Sheet Name: Sheet 1
+---+---+---+
| 1 | 2 | 3 |
+---+---+---+
| 4 | 5 | 6 |
+---+---+---+
Sheet Name: Sheet 2
+-------+-------+-------+
| row 1 | row 2 | row 3 |
+-------+-------+-------+

Writing to a StringIO instance

You need to pass a StringIO instance to Writer:

>>> data = [
...     [1, 2, 3],
...     [4, 5, 6]
... ]
>>> io = StringIO()
>>> sheet = pe.Sheet(data)
>>> sheet.save_to_memory("xls", io)
>>> # then do something with io
>>> # In reality, you might give it to your http response
>>> # object for downloading
