you feel like. As my backer, you will receiveearly access to pyexcel related contents.And your issues will get prioritized if you would like to become my patreon aspyexcel pro user.With your financial support, I will be able to invest
a little bit more time in coding, documentation and writing interesting posts.Known constraintsFonts, colors and charts are not supported.InstallationYou can install pyexcel-htmlr via pip:$pipinstallpyexcel-htmlror clone it and install it:$gitclonehttps://github.com/pyexcel/pyexcel-htmlr.git$cdpyexcel-htmlr$pythonsetup.pyinstallUsageAs a standalone libraryRead from an html fileHere’s the sample code:>>>frompyexcel_htmlrimportget_data>>>data=get_data("your_file.html")>>>importjson>>>print(json.dumps(data)){"Table 1":[[1,2,3],[4,5,6]],"Table 2":[["row 1","row 2","row 3"]]}Read from an html from memoryContinue from previous example:>>># This is just an illustration>>># In reality, you might deal with html file upload>>># where you will read from requests.FILES['YOUR_HTML_FILE']>>>withopen('your_file.html','r')ashtml_file:...io=StringIO(html_file.read().encode())...data=get_data(io)>>>print(json.dumps(data)){"Table 1":[[1,2,3],[4,5,6]],"Table 2":[["row 1","row 2","row 3"]]}Pagination featureLet’s assume the following file is a huge html file:>>>huge_data=[...[1,21,31],...[2,22,32],...[3,23,33],...[4,24,34],...[5,25,35],...[6,26,36]...]>>>sheetx={..."Table 1":huge_data...}>>>pe.save_book_as(dest_file_name="huge_file.html",bookdict=sheetx)And let’s pretend to read partial data:>>>partial_data=get_data("huge_file.html",start_row=2,row_limit=3)>>>print(json.dumps(partial_data)){"Table 1":[[3,23,33],[4,24,34],[5,25,35]]}And you could as well do the same for columns:>>>partial_data=get_data("huge_file.html",start_column=1,column_limit=2)>>>print(json.dumps(partial_data)){"Table 1":[[21,31],[22,32],[23,33],[24,34],[25,35],[26,36]]}Obvious, you could do both at the same time:>>>partial_data=get_data("huge_file.html",...start_row=2,row_limit=3,...start_column=1,column_limit=2)>>>print(json.dumps(partial_data)){"Table 1":[[23,33],[24,34],[25,35]]}As a pyexcel pluginNo longer, explicit import is needed since pyexcel version 0.2.2. Instead,
this library is auto-loaded. So if you want to read data in html format,
installing it is enough.Reading from an html fileHere is the sample code:>>>importpyexcelaspe>>>sheet=pe.get_book(file_name="your_file.html")>>>sheetTable1:+---+---+---+|1|2|3|+---+---+---+|4|5|6|+---+---+---+Table2:+-------+-------+-------+|row1|row2|row3|+-------+-------+-------+Reading from a IO instanceYou got to wrap the binary content with stream to get html working:>>># This is just an illustration>>># In reality, you might deal with html file upload>>># where you will read from requests.FILES['YOUR_HTML_FILE']>>>htmlfile="your_file.html">>>withopen(htmlfile,"rb")asf:...content=f.read()...r=pe.get_book(file_type="html",file_content=content)...print(r)...Table1:+---+---+---+|1|2|3|+---+---+---+|4|5|6|+---+---+---+Table2:+-------+-------+-------+|row1|row2|row3|+-------+-------+-------+LicenseNew BSD LicenseDeveloper guideDevelopment steps for code changesgit clonehttps://github.com/pyexcel/pyexcel-htmlr.gitcd pyexcel-htmlrUpgrade your setup tools and pip. They are needed for development and testing only:pip install –upgrade setuptools pipThen install relevant development requirements:pip install -r rnd_requirements.txt # if such a file existspip install -r requirements.txtpip install -r tests/requirements.txtOnce you have finished your changes, please provide test case(s), relevant documentation
and update CHANGELOG.rst.NoteAs to rnd_requirements.txt, usually, it is created when a dependent
library is not released. Once the dependecy is installed
(will be released), the future
version of the dependency in the requirements.txt will be valid.How to test your contributionAlthoughnoseanddoctestare both used in code testing, it is adviable that unit tests are put in tests.doctestis incorporated only to make sure the code examples in documentation remain valid across different development releases.On Linux/Unix systems, please launch your tests like this:$ makeOn Windows systems, please issue this command:> test.batBefore you commitPlease run:$ make formatso as to beautify your code otherwise travis-ci may fail your unit test.And make sure you would have run moban commandAdditional steps are required:pip install mobanmake your changes in.moban.ddirectory, then issue commandmobanmobanotherwise travis-ci may also fail your unit test.What is .moban.d.moban.dstores the specific meta data for the library.Change log0.6.0 - 9.10.2020UpdatedNew style xlsx plugins, promoted by pyexcel-io v0.6.20.5.2 - 23.10.2017updatedpyexcelpyexcel#105,
