Change log

0.5.0 - unreleased

Added

  1. Sheet.top() and Sheet.top_left() for data browsing
  2. add html as default rich display in Jupyter notebook. It is dependent on pyexcel-text.
  3. new dictionary source supported: a dictionary of key value pair could be read into a sheet.
  4. added dynamic external plugin loading. meaning if a pyexcel plugin is installed, and has __pyexcel_plugins__ signature in its __init__.py, it will be loaded implicitly. And this change would remove un-necessary info log for those who do not use pyexcel-text and pyexcel-chart
  5. save_book_as before 0.5.0 becomes isave_book_as and save_book_as in 0.5.0 convert BookStream to Book before saving.

Removed

  1. pyexcel.Writer and pyexcel.BookWriter were removed
  2. pyexcel.load_book_from_sql and pyexcel.load_from_sql were removed
  3. pyexcel.deprecated.load_from_query_sets, pyexcel.deprecated.load_book_from_django_models and pyexcel.deprecated.load_from_django_model were removed

0.4.4 - 06.02.2017

Updated

  1. #68: regression save_to_memory() should have returned a stream instance which has been reset to zero if possible. The exception is sys.stdout, which cannot be reset.
  2. #74: Not able to handle decimal.Decimal

Removed

  1. remove get_{{file_type}}_stream functions from pyexcel.Sheet and pyexel.Book introduced since 0.4.3.

0.4.3 - 26.01.2017

Added

  1. '.stream' attribte are attached to ~pyexcel.Sheet and ~pyexcel.Book to get direct access the underneath stream in responding to file type attributes, suchs sheet.xls. it helps provide a custom stream to external world, for example, Sheet.stream.csv gives a text stream that contains csv formatted data. Book.stream.xls returns a xls format data in a byte stream.

Updated

  1. Better error reporting when an unknown parameters or unsupported file types were given to the signature functions.

0.4.2 - 17.01.2017

Updated

  1. Raise exception if the incoming sheet does not have column names. In other words, only sheet with column names could be saved to database. sheet with row names cannot be saved. The alternative is to tranpose the sheet, then name_columns_by_row and then save.
  2. fix iget_records where a non-uniform content should be given, e.g. [["x", "y"], [1, 2], [3]], some record would become non-uniform, e.g. key 'y' would be missing from the second record.
  3. skip_empty_rows is applicable when saving a python data structure to another data source. For example, if your array contains a row which is consisted of empty string, such as ['', '', '' ... ''], please specify skip_empty_rows=False in order to preserve it. This becomes subtle when you try save a python dictionary where empty rows is not easy to be spotted.
  4. #69: better documentation for save_book_as.

0.4.1 - 23.12.2016

Updated

  1. #68: regression save_to_memory() should have returned a stream instance.

0.4.0 - 22.12.2016

Added

  1. Flask-Excel issue 19 allow sheet_name parameter

0.3.0 - 28.10.2016

Added:

  1. file type setters for Sheet and Book, and its documentation
  2. iget_records returns a generator for a list of records and should have better memory performance, especially dealing with large csv files.
  3. iget_array returns a generator for a list of two dimensional array and should have better memory performance, especially dealing with large csv files.
  4. Enable pagination support, and custom row renderer via pyexcel-io v0.2.3

Updated

  1. Take isave_as out from save_as. Hence two functions are there for save a sheet as
