Let&rsquo;s discuss the reasons for the error and the solutions to fix it.<\/p><h2 class=\"wp-block-heading\" id=\"reasons-for-the-error-&ldquo;an-unexpected-error-has-occurred&rdquo;-in-excel\">Reasons for the Error &ldquo;An Unexpected Error has Occurred&rdquo; in Excel<\/h2><p>Some possible causes of this error are:<\/p><ul class=\"wp-block-list\">\n<li>Excel version incompatibility<\/li>\n\n\n\n<li>Incompatible or faulty third-party add-ins<\/li>\n\n\n\n<li>Restricted permissions<\/li>\n\n\n\n<li>Hardware or software issues<\/li>\n\n\n\n<li>Network connection error<\/li>\n\n\n\n<li>Lack of disk space<\/li>\n\n\n\n<li>Corrupted Excel file<\/li>\n<\/ul><h2 class=\"wp-block-heading\" id=\"methods-to-fix-the-excel-error-&ldquo;an-unexpected-error-has-occurred&rdquo;\">Methods to Fix the Excel Error &ldquo;An Unexpected Error has Occurred&rdquo;<\/h2><p>Following are some solutions you can try to fix this Excel error.<\/p><h3 class=\"wp-block-heading\">Method 1: Check the Folder Permissions<\/h3><p>You should have read, write, modify, and delete permissions to save an Excel file to a network drive. However, if you don&rsquo;t have such permissions, you may get the unexpected error has occurred message. In such a case, you can contact the file owner to assign you the required permissions.<\/p><h3 class=\"wp-block-heading\">Method 2: Save the File to an Alternative Drive<\/h3><p>Sometimes, the file-saving process may get interrupted due to lack of space on drive or some drive issues. You can try saving the file to another drive.<\/p><h3 class=\"wp-block-heading\" id=\"h-method-3-check-third-party-add-ins\">Method 3: Check Third-Party Add-Ins<\/h3><p>Sometimes, third-party add-ins can prevent you from saving an Excel file. To check if any third-party Excel add-ins are causing the error in Excel, you can try to save the file in Safe Mode. To do this, follow these steps:<\/p><ul class=\"wp-block-list\">\n<li>Close the Excel Application.<\/li>\n\n\n\n<li>Go to <strong>Start &gt; Programs <\/strong>and open<strong> Microsoft Excel<\/strong>.<\/li>\n\n\n\n<li>As Excel starts, press and hold the <strong>Ctrl<\/strong> key until the message &ldquo;You&rsquo;re holding down the Ctrl key. Do you want to start Excel in safe mode&rdquo; appears.<\/li>\n<\/ul><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"415\" height=\"154\" src=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/01\/excel-in-safe-mode-window.png\" alt=\"Image of opening Excel In Safe Mode Window to fix the unexpected error\" class=\"wp-image-121694 apply-gradient-on-post-images\" srcset=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/01\/excel-in-safe-mode-window.png 415w, https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/01\/excel-in-safe-mode-window-300x111.png 300w\" sizes=\"auto, (max-width: 415px) 100vw, 415px\" \/><\/figure><ul class=\"wp-block-list\">\n<li>Click <strong>Yes<\/strong>.<\/li>\n<\/ul><p>Now, open a new Excel file and try to save it. If that works, then try to save the problematic Excel file.<\/p><p>If the error is fixed, you can save the file, and then locate and disable the problem-causing Excel add-in to eliminate the issue. To disable the Excel add-in, follow these steps:<\/p><ul class=\"wp-block-list\">\n<li>Go to <strong>File &gt; Options &gt; Add-ins<\/strong>.<\/li>\n<\/ul><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"829\" height=\"681\" src=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/01\/excel-options-to-select-addins.png\" alt=\"Image of Excel Options To Select Addins to fix unexpected error\" class=\"wp-image-121695 apply-gradient-on-post-images\" srcset=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/01\/excel-options-to-select-addins.png 829w, https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/01\/excel-options-to-select-addins-300x246.png 300w, https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/01\/excel-options-to-select-addins-768x631.png 768w\" sizes=\"auto, (max-width: 829px) 100vw, 829px\" \/><\/figure><ul class=\"wp-block-list\">\n<li>In the <strong>Manage<\/strong> field, click <strong>Excel Add-ins<\/strong> and then click <strong>Go<\/strong>.<\/li>\n<\/ul><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"287\" height=\"399\" src=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/01\/addins-window.png\" alt=\"Addins Window\" class=\"wp-image-121696 apply-gradient-on-post-images\" srcset=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/01\/addins-window.png 287w, https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/01\/addins-window-216x300.png 216w\" sizes=\"auto, (max-width: 287px) 100vw, 287px\" \/><\/figure><ul class=\"wp-block-list\">\n<li>In the <strong>Add-ins available<\/strong> field, clear the checkbox next to the add-in to disable it and click <strong>OK<\/strong>.<\/li>\n<\/ul><p class=\"note-alert\"><strong>Note<\/strong>:&nbsp;Disabling the add-in does not remove it from the system.

Sometimes, Excel fails to save the file when the &ldquo;Ignore other applications that use DDE&rdquo; option is enabled. You can disable this option using the below steps:<\/p><ul class=\"wp-block-list\">\n<li>Open your Excel application.<\/li>\n\n\n\n<li>Select <strong>File &gt; Options.<\/strong><\/li>\n<\/ul><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"130\" height=\"522\" src=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/01\/option-display-window-1.png\" alt=\"Option Display Window\" class=\"wp-image-121701 apply-gradient-on-post-images\" srcset=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/01\/option-display-window-1.png 130w, https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/01\/option-display-window-1-75x300.png 75w\" sizes=\"auto, (max-width: 130px) 100vw, 130px\" \/><\/figure><ul class=\"wp-block-list\">\n<li>Click the <strong>Advanced<\/strong> option, scroll down to the General section and then un-select the &ldquo;<strong>Ignore other applications that use<\/strong> <strong>Dynamic Data Exchange (DDE<\/strong>)&rdquo;&nbsp;checkbox.<\/li>\n<\/ul><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"829\" height=\"681\" src=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/01\/excel-options-to-select-addins-1.png\" alt=\"Select Ignore Applications That Use Dynamic Data Exchange Window\" class=\"wp-image-121698 apply-gradient-on-post-images\" srcset=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/01\/excel-options-to-select-addins-1.png 829w, https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/01\/excel-options-to-select-addins-1-300x246.png 300w, https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/01\/excel-options-to-select-addins-1-768x631.png 768w\" sizes=\"auto, (max-width: 829px) 100vw, 829px\" \/><\/figure><ul class=\"wp-block-list\">\n<li>Click&nbsp;<strong>OK<\/strong>.<\/li>\n<\/ul><h3 class=\"wp-block-heading\">Method 5: Repair Corrupted Excel File<\/h3><p>If your Excel file is corrupted, you may get the &ldquo;An unexpected error has occurred. Changes to your data cannot be saved&rdquo; error when saving the file. In this case, you can use the Microsoft built-in utility &ndash; <strong>Open and Repair<\/strong> &ndash; to repair the damaged or corrupted Excel file. Follow these steps:<\/p><ul class=\"wp-block-list\">\n<li>In Excel, go to&nbsp;<strong>File &gt;&nbsp;Open &gt; Browse<\/strong>.&nbsp;<\/li>\n\n\n\n<li>In the&nbsp;Open&nbsp;dialog box, click on the corrupted Excel file.&nbsp;<\/li>\n\n\n\n<li>Click the arrow next to the&nbsp;Open&nbsp;button and select&nbsp;<strong>Open and Repair<\/strong>&nbsp;from the dropdown.<\/li>\n\n\n\n<li>Select&nbsp;<strong>Repair<\/strong>&nbsp;to recover as much data from the file as possible.<\/li>\n<\/ul><p>The Open and Repair utility can only fix minor issues with Excel files. Sometimes, the tool may stop working, crash, or show an exception. The built-in tool may fail when the file is severely corrupted. In such cases, you can use an advanced <a href=\"https:\/\/www.stellarinfo.com\/repair-excel-file.php\" target=\"_blank\" rel=\"noreferrer noopener\">Excel repair tool<\/a>, like Stellar Repair for Excel. This tool is recommended by certified Excel experts to repair corrupt .xls, .xlsx, .xltm, .xltx, and .xlsm files. It can recover all the Excel file components, like formulas, pivot tables, formulas, etc. It supports all Microsoft Excel versions.&nbsp;<\/p><h2 class=\"wp-block-heading\" id=\"closure\">Closure<\/h2><p>Many users have reported encountering the &lsquo;unexpected error&rsquo; when trying to export Excel reports from SharePoint Online to Excel or while saving the Excel file. The error may occur due to several reasons. You can apply the solutions as discussed above to resolve the issue. Sometimes, you encounter the error due to corruption in the Excel file. In this case, try to repair the file using the Open and Repair tool. If it doesn&rsquo;t work, you can use Stellar Repair for Excel which can easily repair the severely corrupted Excel file and recover all the data with 100% integrity.<\/p><p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>When saving an Excel file if the saving process is interrupted, you&hellip; <a class=\"more-link\" href=\"https:\/\/www.stellarinfo.com\/blog\/an-unexpected-error-has-occurred-changes-to-your-data-cannot-be-saved\/\">Continue reading <span class=\"screen-reader-text\">[2025 Fix]: An Unexpected Error has Occurred.
