Let me tell you about IMPORTHTML()...
So here's all the code you need in Google Sheets:
=IMPORTHTML("https://en.wikipedia.org/wiki/Transistor_count", "table", 12) The import seems to work fine: 
And it's possible to download the table as CSV:
Processor,Transistor count,Date of introduction,Designer,MOS process,Area "MP944 (20-bit, *6-chip*)",,1970[14] (declassified 1998),Garrett AiResearch,, "Intel 4004 (4-bit, 16-pin)","2,250",1971,Intel,"10,000 nm",12 mm² "Intel 8008 (8-bit, 18-pin)","3,500",1972,Intel,"10,000 nm",14 mm² "NEC μCOM-4 (4-bit, 42-pin)","2,500[17][18]",1973,NEC,"7,500 nm[19]",*?* Toshiba TLCS-12 (12-bit),"over 11,000[20]",1973,Toshiba,"6,000 nm",32 mm² "Intel 4040 (4-bit, 16-pin)","3,000",1974,Intel,"10,000 nm",12 mm² "Motorola 6800 (8-bit, 40-pin)","4,100",1974,Motorola,"6,000 nm",16 mm² ... ... You'll just need to clean the numbers up, which you'd have to do anyway with the API or by scraping with BeautifulSoup.
