EmDashify — Em Dashes Made Easy
The Python library you think you'll never need—until you use it more than the ones you do.
Why?
ChatGPT, Claude, and other large language models often use the em dash (—) when answering users. It's become especially noticeable in AI-generated responses: Pew Research Center found that em dashes appeared about twice as often in the English-language web text it studied as in 2023. Of course, the em dash predates AI—it's ordinary punctuation, not proof that a text was AI-written.
Yet most QWERTY keyboards have a - key, not a dedicated — key. EmDashify lets you type -- and turn it into a proper em dash in text, Markdown, or Word documents. No AI needed. Just punctuation.
Quick start
pip install emdashify
emdashify "Hello -- world"
# Hello — world
from emdashify import convert
convert("Hello -- world") # 'Hello — world'
convert("hello--world", compact=True) # 'hello—world'
Word documents (.docx)
Convert an entire Word document, including paragraphs, tables, headers and footers, without flattening text formatting. Install the optional Word extra:
pip install "emdashify[word]"
emdashify --file draft.docx --output draft-fixed.docx
emdashify --file draft.docx --check
from emdashify import convert_docx
convert_docx("draft.docx", "draft-fixed.docx")
The original file is never overwritten. Word support is for .docx, not legacy .doc. Review complex documents with tracked changes or advanced Word fields after conversion.
Text and Markdown files
emdashify --file notes.md --diff
emdashify --file notes.md --output notes-fixed.md
emdashify --file notes.md --check
Safe by default: only standalone -- becomes —. Flags (--help), dates, and --- stay unchanged; Markdown code blocks are protected. Use --compact for word--word.
Requires Python 3.10+. For development or publishing, see release instructions.
