The hyperlinks are not clickable because the text-based format does not support interactive elements such as hyperlinks. In a text-based format, the hyperlinks are simply displayed as text and do not have the functionality to redirect the user to another webpage. To access the linked content, the user would need to manually copy and paste the URL into a web browser. **

The Excel formula for hyperlinks is =HYPERLINK(link_location, [friendly_name]). The link_location is the address of the webpage or file you want to link to, and the friendly_name is the text that will be displayed in the cell as the hyperlink. This formula allows you to create clickable links within your Excel spreadsheet. **

To create hyperlinks to headings in a document, you can follow these steps: 1. First, navigate to the heading you want to link to and select it. 2. Right-click on the selected heading and choose "Copy link address" or a similar option depending on your word processing software. 3. Then, go to the text or image where you want to insert the hyperlink, highlight it, and click on the insert/edit link option. 4. Paste the copied link address into the URL field and save the changes. Now, when someone clicks on the hyperlink, it will take them directly to the heading you linked to. **

In a PDF document, hyperlinks typically appear as underlined text or as clickable elements. When clicked, hyperlinks can direct the reader to another page within the document, an external website, or a different section of the PDF. The appearance of hyperlinks can vary depending on the software used to view the PDF, but they generally retain their functionality to navigate to the specified destination. Additionally, some PDF viewers may provide options to customize the display of hyperlinks, such as changing the color or style of the linked text. **

Hyperlinks in Excel can mysteriously break due to various reasons such as changes in the file location, renaming of the file, or moving the file to a different folder. Additionally, if the linked file is deleted or the network location is changed, the hyperlink can also break. It is important to regularly check and update hyperlinks in Excel to ensure they are functioning properly. **

To number hyperlinks in Excel, you can use the HYPERLINK function combined with the ROW function. For example, if you want to number the hyperlinks in column A, you can use the formula =HYPERLINK("URL","Link"&ROW()). This will create hyperlinks with numbered text. You can then drag the formula down to apply it to multiple cells. **

You can automatically insert hyperlinks in Excel by using the HYPERLINK function. This function allows you to create a clickable hyperlink within a cell by specifying the link address and the display text. Simply enter the HYPERLINK function in the formula bar, providing the link address and the display text as arguments. Once the function is entered, the cell will display the display text as a clickable hyperlink that directs to the specified link address. **

There could be several reasons why Excel hyperlinks are not working anymore. One common reason is that the file containing the hyperlinks has been moved or renamed, causing the links to break. Another reason could be that the hyperlink address has been changed or is no longer valid. Additionally, there may be an issue with the Excel program itself, such as a software glitch or corruption. It's important to troubleshoot and identify the specific cause in order to fix the issue. **
