This article will explain in detail how to use Python to achieve office automation PPT batch conversion operation, the editor thinks it is very practical, so share it for you to do a reference, I hope you can get something after reading this article.

PPT is divided into content and format, using Python to operate PPT, is to use Python to obtain and fill the content of PPT, modifying the format of PPT is not the strength of Python. So, when you have a bunch of PPT to do, make a formatted PPT, then copy the PPT file with Python, and then read and write it.

Installation of python-pptx module

Pip install python-pptx

Read PPT

If the file "Test .pptx" reads as follows:

Then the following code can read its contents:

From pptx import Presentationprs = Presentation ("test .pptx") for index Slide in enumerate (prs.slides): print (f "page {index+1}") for shape in slide.shapes: if shape.has_text_frame: text_frame = shape.text_frame # print (text_frame.text) # if read in segments, use the following code for paragraph in text_frame.paragraphs: print (paragraph.text)

The execution result is as follows:

Write to PPT

Let's start with a simpler one.

If you want to generate the PPT page shown in the following figure

The code can be written as follows:

From pptx import Presentationprs = Presentation () title_slide_layout = prs.slide_layouts [0] slide = prs.slides.add_slide (title_slide_layout) title = slide.shapes.titlesubtitle = slide.placeholders [1] title.text = "Hello, World!" subtitle.text = "python-pptx was here!" prs.save ('test.pptx') add a slide

All slides have panels. Similarly, pptx provides nine layouts for us to choose from, which are:

Title (presentation title slide)

Title and Content

Section Header (sometimes called Segue)

Two Content (side by side bullet textboxes)

Comparison (same but additional title for each side by side content box)

Title Only

Blank

Content with Caption

Picture with Caption

Corresponding to the following layout of PPT, I have marked them one by one with data:

For example, to add the layout of a title and content, you can write the code like this:

From pptx import Presentationprs = Presentation () SLD_LAYOUT_TITLE_AND_CONTENT = 1 # # title and content layout serial number slide_layout = prs.slide_ layouts [SLD _ LAYOUT_TITLE_AND_CONTENT] slide = prs.slides.add_slide (slide_layout) add content to the slide

Understand the shape before adding content. Technically, you can place nine types of shapes on a slide:

Shapes-automatic shapes with fills and outlines

Text box-automatic shape without fills and outlines

Placeholder-an automatic shape that can appear on a slide layout or master and inherited on slides that use that layout, allowing content in placeholder format to be added

Line / connector

Picture

Table-things in rows and columns

Chart-pie chart, line chart, etc.

Smart Art-not supported yet, but retained if present

Media clips-video or audio

Each slide is organized by a shape tree, which is called a tree because it is generally hierarchical; a node in a shape tree can be a group shape, which itself can contain shapes and have the same semantics as the shape tree. For most uses, the shape tree has list semantics.

Get the shape in the slide:

Shapes = slide.shapes

Automatic shapes are regular shapes. Squares, circles, triangles, stars and so on. There are 182 different shapes to choose from. 120 of them have adjustment "handles" that you can use to change shapes.

Many shape types share a common set of properties. We will introduce many of these shapes here, because some of them are just a special form of AutoShape.

Add Auto Shap

The following code adds a rounded rectangle shape, one inch square, and places it one inch from the upper-left corner of the slide:

From pptx.enum.shapes import MSO_SHAPEfrom pptx.util import Inchesshapes = slide.shapesleft = top = width = height = Inches (1.0) shape = shapes.add_shape (MSO_SHAPE.ROUNDED_RECTANGLE, left, top, width, height) prs.save ('New Slide .pptx')

For a list of all 182 automatic shape types, see the MSO_AUTO_SHAPE_TYPE enumeration item in the official document.

Placeholder

A placeholder is also a shape, with 18 types of placeholders. Title, central title, subtitle, body, content, picture, clip art, chart, table, smart art, date, footer, slide number, media clip, title, vertical text, vertical object, vertical title.

Placeholders on slides can be empty or populated. This is most obvious in picture placeholders. When unpopulated, the placeholder displays customizable prompt text. Content-rich placeholders also display one or more content insert buttons when empty.

The plain text placeholder enters fill mode when entering the first character of the text and returns to unfilled mode when the last character of the text is deleted. Rich placeholders enter fill mode when inserting content such as a picture, and return to unfilled mode when the content is deleted. In order to delete the filled placeholder, the shape must be deleted twice. Delete the deleted content for the first time and restore the placeholder to unpopulated mode. Additional deletions delete the placeholder itself. You can restore deleted placeholders by reapplying the layout.

Access placeholder > prs = Presentation () > slide = prs.slides.add_slide (prs.slide_layouts [8]) > for shape in slide.placeholders:... Print ('d% s'% (shape.placeholder_format.idx, shape.name))... 0 Title 11 Picture Placeholder 22 Text Placeholder 3

If you already know the index of the placeholder, you can also access it through the index:

> slide.placeholders [1] > slide.placeholders [2] .name'Text Placeholder 3' insert content placeholder > prs = Presentation () > slide = prs.slides.add_slide (prs.slide_layouts [8]) > placeholder = slide.placeholders [1] # idx key Not position > > placeholder.name'Picture Placeholder 2'> placeholder.placeholder_format.typePICTURE (18) > > picture = placeholder.insert_picture ('my-image.png') if you want to insert the table: from pptx import Presentationfrom pptx.util import Inchesprs = Presentation () title_only_slide_layout = prs.slide_layouts [5] slide = prs.slides.add_slide (title_only_slide_layout) shapes = slide.shapesshapes.title.text =' Adding a Table'rows = cols = 2left = top = Inches (2. 0) width = Inches (6 0) height = Inches (0 8) table = shapes.add_table (rows Cols, left, top, width, height). Table# set column widthstable.columns [0] .width = Inches (2.0) table.columns [1] .width = Inches (4.0) # write column headingstable.cell (0,0). Text = 'Foo'table.cell (0,1). Text =' Bar'# write body cellstable.cell (1,0). Text = 'Baz'table.cell (1) 1). Text = 'Qux'prs.save (' write_ppt_table.pptx') if you want to insert a chart: from pptx import Presentationfrom pptx.chart.data import CategoryChartDatafrom pptx.enum.chart import XL_CHART_TYPEfrom pptx.util import Inches# create presentation with 1 slide-prs = Presentation () slide = prs.slides.add_slide (prs.slide_layouts [5]) # define chart data-chart_ Data = CategoryChartData () chart_data.categories = ['East' 'West',' Midwest'] chart_data.add_series ('Series 1, (19.2, 21.416.7)) # add chart to slide-x, y, cx, cy = Inches (2), Inches (2), Inches (6), Inches (4.5) slide.shapes.add_chart (XL_CHART_TYPE.COLUMN_CLUSTERED, x, y, cx, cy Chart_data) prs.save ('write_ppt_chart.pptx') PPT to Pdf

The following methods apply to windows only

Def PPTtoPDF2 (inputFileName, outputFileName, formatType = 32): import comtypes.client powerpoint = comtypes.client.CreateObject ("Powerpoint.Application") powerpoint.Visible = 1 if outputFileName [- 3:]! = 'pdf': outputFileName = outputFileName + ".pdf" deck = powerpoint.Presentations.Open (inputFileName) deck.SaveAs (outputFileName) FormatType) # formatType = 32 for ppt to pdf deck.Close () powerpoint.Quit () this is the end of the article on "how to use Python to implement PPT batch conversion operations in office automation" Hope that the above content can be helpful to you, so that you can learn more knowledge, if you think the article is good, please share it for more people to see.
