Numdex

Extract numeric codes from URLs, jump to related pages, and save ratings and notes per code. JSON import/export.

When you access a web page, this extension extracts a sequence of four or more consecutive digits (such as a stock code or zip code) from the current page URL. You can select a jump destination with the digits from the right-click menu. You can also rate the digits as good, neutral, or bad, and save the rating. You can keep a memo for each digit, and there is a button to easily append the current tab’s title to your memo. For example, if you are searching for rental properties in Mountain View on Zillow and visit https://www.zillow.com/homes/for_rent/94041_rb/ using this extension, the number "94041" (the zip code) will be extracted. You can then jump to the search results for nearby Bank of America branches or ATMs: https://locators.bankofamerica.com/?q=94041 If you like Mountain View, you can rate the digits - "94041" as good and keep it in your Chrome. I live in Japan and created this extension to jump from Yahoo Finance Japan’s page https://finance.yahoo.co.jp/quote/7974.T to Minkabu’s page https://minkabu.jp/stock/7974 and save ratings of stocks. The extracted number will be added to the end of the specified URL in the settings screen. If you want to insert the extracted number in the middle of the URL, you can use %s in the URL, and the number will be placed there. Example: https://finance.yahoo.co.jp/quote/%s.T Your ratings and memos are stored per number and can be deleted at any time. The 10 most recent ratings are displayed as a list, and you can quickly jump to the corresponding URLs from the list. You can also view all your rating history in a separate screen. This extension is free, but there is a “Buy me a coffee” link in the settings screen.
