The Excel Hyperlink Extractor produces a plain-text inventory of http, https, and mailto cell hyperlinks stored in a local .xlsx workbook, returning the worksheet name, cell address, and normalized URL for each retained target without uploading the file or following any link. A pre-removal audit is the missing step most skip, because the chart-to-workbook reference and the cell hyperlinks inside the workbook are two different things: PowerPoint owns the data link, while Excel owns the clickable targets that travel with the file. The audit gives you both numbers before you decide which link to break and which workbook to keep. The browser never executes a macro, refreshes an external data connection, calculates a formula, inspects an image, or modifies the workbook. The report caps at 1,000 safe links, the workbook stays in your current tab, and the result downloads as plain text for review, handoff, or comparison.
What Linking an Excel Chart to PowerPoint Actually Does
When an Excel chart is pasted into PowerPoint, the slide may receive an embedded OLE object, a linked chart that updates when the source workbook changes, or a static picture. A linked chart stores a reference path back to the .xlsx file on disk, which is the link most people mean when they search how to remove the Excel link from a PPT chart. Every save in the workbook tries to refresh the chart on the slide, even after the receiving user closes and reopens the deck.
Parallel to that data link, the Excel workbook can also hold cell hyperlinks: http, https, and mailto targets attached to individual cells. Those cell hyperlinks travel inside the workbook and are not the chart data link, but they do matter when the workbook is shared, copied, or emailed along with the slide. Before breaking the chart link, it is worth knowing exactly which clickable targets are sitting in the worksheet, because each retained URL is one more item a viewer might open from inside the file.
Audit Stored Hyperlinks in the Excel Workbook First
Running a pre-removal audit serves three concrete jobs. First, it confirms whether the workbook actually contains external cell hyperlinks at all. A common surprise is visible text that looks like a URL yet has no clickable attachment, and a link-removal checklist needs to know the difference. Second, it pins every retained target to a worksheet name and cell address, so you can decide which cells to clear, which to keep, and which to open in a trusted browser before anyone else touches them. Third, the report is plain text, which makes it easy to diff against an earlier extract or to attach to a change ticket when the PPT chart link is being severed.
The Excel Hyperlink Extractor is built around that audit: it reads the stored hyperlink targets already attached to worksheet cells in a local .xlsx file and lists them in the worksheet-and-cell order they were found. The workbook stays in the current browser tab, is not uploaded to Lizely, and is never modified. Cells that merely display text such as https://example.com with no actual hyperlink attachment are deliberately skipped, because the audit is meant to list real clickable references rather than text that resembles a URL.
Run the Excel Hyperlink Extractor on the Workbook
Open the tool in your browser and prepare the .xlsx file the PPT chart is pulling data from.
- Choose one local .xlsx workbook no larger than 20 MB from your computer.
- Confirm the file opens cleanly and contains the worksheet your PPT chart references.
- Select Extract safe links to inspect stored external cell hyperlink targets.
- Review the worksheet name and cell address beside each retained URL in the resulting plain-text report.
- Download the plain-text report if you need to attach it to a change ticket or compare it against an earlier extract.
The result page renders as a plain textarea rather than a clickable rich preview, so copying a row into a ticket or a diff tool does not turn the report into a browser navigation action. Every retained target is normalized through the browser URL parser before deduplication, so two cells pointing to https://example.com and HTTPS://Example.com collapse into a single first-seen entry plus a duplicate marker for the second.
Read the Report With Worksheet and Cell in Mind
Each line in the report tells you three things: the worksheet name, the cell address, and the normalized URL. That location data answers a practical question: is the link the chart moves around sitting in the same cells the chart reads from, or in an unused corner of the sheet? Cross-referencing the cell address back to the chart legend or data range helps you isolate which retained URLs the chart actually depends on. The extractor preserves the first occurrence of each normalized URL and reports later occurrences as duplicates rather than printing them indefinitely.
| Target Type Seen by the Audit | Report Status |
|---|---|
| http://example.com | Retained and normalized |
| https://example.com/path | Retained and normalized |
| mailto:[email protected] | Retained and normalized |
| Relative path or internal workbook anchor | Rejected on purpose |
| file:// or UNC path | Rejected on purpose |
| data: or javascript: URL | Rejected on purpose |
| Malformed value or control-character payload | Rejected on purpose |
| Target over the stated length bound | Rejected on purpose |
| Visible cell text that looks like a URL | Skipped (no hyperlink attached) |
Input limits also matter before you start. The workbook must be a non-empty classic .xlsx package no larger than 20 MB, with a single-disk OOXML ZIP directory, at most 2,000 entries, and no more than 50 MB of declared expanded data. A sheet may contain at most 100,000 addressed cells, and the complete report is capped at 1,000 safe links. Damaged, encrypted, Zip64, legacy .xls, macro-enabled, multi-disk, or oversized packages stop with a visible error, so the browser does not silently skip an over-limit workbook and pretend its link list is complete.
What the Extractor Deliberately Skips
The audit is built around a narrow rule: only normalized http, https, and mailto targets that are actually attached to worksheet cells are retained. Relative paths, internal workbook anchors, file URLs, data URLs, JavaScript URLs, malformed values, control-character payloads, and targets over the length bound are rejected on purpose. The boundary exists because an extracted report should not turn an untrusted spreadsheet into a browser navigation action if someone copies a row into a different tool.
Text that looks like a URL but is not a real hyperlink is also skipped. A cell that contains https://example.com as a label, with no attached link, is outside the tool's scope. Formulas that produce URL-looking strings, hidden workbook connections, embedded web content, and Word-style relationships are out of scope. The result is a bounded, local inventory of safe external targets that were already stored as Excel cell hyperlinks when the workbook was last saved.
Disconnect the PPT Chart Link After the Audit
With a clean link report in hand, the actual chart-to-workbook disconnection is a PowerPoint operation rather than an Excel one. Open the slide, select the chart, choose Chart Object, and use Break Link to detach the data feed from the current workbook. To make the disconnection permanent, copy the chart, then paste it back as a picture through Paste Special, choosing PNG or Enhanced Metafile (EMF) so the slide no longer carries a live reference to the .xlsx file. If the source workbook has been moved or renamed, PowerPoint prompts you through File, Info, Edit Links to Files, where the same dialog lets you sever the link explicitly.
The Excel Hyperlink Extractor makes that step cheaper because the report confirms which cells and which URLs sit inside the workbook before anything disconnects. Once the list is in hand, hand it to the person maintaining the file, scrub the workbook if any retained target looks unfamiliar, and only then break the chart link in the slide. For an unfamiliar workbook, run the extractor on a smaller representative copy first, decide which targets belong there, and treat the chart-to-workbook disconnection as a deliberate snapshot rather than a routine save.
