Streamline your workflow by combining documents from OneDrive or other platforms." --- # Merge documents using Power Automate In this guide, you’ll learn how to combine and merge multiple files to PDF using Power Automate. Nutrient supports converting a wide range of file types to PDF in Power Automate. For more information, refer to the list of [supported file formats](https://www.nutrient.io/guides/document-converter/sharepoint/knowledge-base/what-file-formats-types-are-supported-for-conversion.md). In this example, you’ll build a flow that will loop through all the documents in a OneDrive for Business folder once a day, merge them, and then create a merged PDF document in a different location of your choice. This example combines documents in OneDrive, but you can easily merge multiple documents and save them to another destination like Dropbox, Google Drive, SharePoint, or any platform supported by Power Automate. ### Prerequisites Before beginning, ensure the following prerequisites are in place: - An Office 365 subscription with Power Automate and OneDrive for Business support. - A full or free trial subscription to Nutrient’s [Document Converter for Power Automate](https://www.nutrient.io/low-code/try/converter-power-automate/). - Appropriate privileges to create flows. - Working knowledge of Microsoft Power Automate. ### High-level overview The image below shows a high-level overview of how to merge documents using Power Automate.![merge documents flow](@/assets/guides/muhimbi/pdf-converter/power-automate/merge-documents-1.jpg) ### Merging documents using Power Automate First create a scheduled cloud flow and then enter a name in the **Flow name** field. Include the starting date and time, and set it to repeat every day. Press **Create**.![create cloud flow](@/assets/guides/muhimbi/pdf-converter/power-automate/merge-documents-2.jpg) Insert the **Initialize variable** flow action to store the merged contents. Give this action a suitable name, and set the **Type** field to **String**. Leave the **Value** field empty.![variable flow action](@/assets/guides/muhimbi/pdf-converter/power-automate/merge-documents-3.jpg) Insert the **Initialize variable** flow action to store the merged count. Set the **Type** field to **Integer** and leave the **Value** field empty.![initialize variable flow action](@/assets/guides/muhimbi/pdf-converter/power-automate/merge-documents-4.jpg) Add the OneDrive for Business **List files in folder** action, and specify the path in the **Folder** field. This contains all the files that need to be merged.![list files in folder](@/assets/guides/muhimbi/pdf-converter/power-automate/merge-documents-5.jpg) Insert the **Apply to each** loop, and add the **Output(value)** of the **List files in folder** action.![apply to each loop](@/assets/guides/muhimbi/pdf-converter/power-automate/merge-documents-6.jpg) Insert the **Add a condition** action. Specify **Is folder?**, which is the output of the **List files in folder** action, and set it to **false**.![add a condition action](@/assets/guides/muhimbi/pdf-converter/power-automate/merge-documents-7.jpg) If the step above evaluates to `true`, add the **Get file content using path** action. In the **File Path** field, specify the **Path** variable, which is the output of the **List files in folder** action.![list files in folder](@/assets/guides/muhimbi/pdf-converter/power-automate/merge-documents-8.jpg) Insert the **Add a condition** action. Insert **Merged Count**, which is the output of **Initialize variable – Merged Count**, and set it to **0**.![add a condition action](@/assets/guides/muhimbi/pdf-converter/power-automate/merge-documents-9.jpg) If the step above evaluates to `true`, add the Nutrient **Convert document** action. The action has two parameters: - **Source file name** — The name is the output of the **List files in folder** action. - **Source file content** — **File content** is the output of the **Get file content using path** action.![source file content](@/assets/guides/muhimbi/pdf-converter/power-automate/merge-documents-10.jpg) Insert the OneDrive for Business **Create file** action after the **Convert document** action. The action has three main parameters: - **Folder Path** — This is the path of your destination folder. - **File Name** — You can create a variable for the file name, if needed. This example uses **MergeFile.PDF**. - **File Content** — This is **Processed files content**, which is the output of the **Convert document** action.![convert document action](@/assets/guides/muhimbi/pdf-converter/power-automate/merge-documents-11.jpg) If the step above evaluates to `false` instead of `true` — i.e. **Merged Count** isn’t equal to **0** — add the **Get file content using path** action. In the **File Path** field, specify the **Path** variable, which is the output of the **List files in folder** action.![get file content using path](@/assets/guides/muhimbi/pdf-converter/power-automate/merge-documents-12.jpg) Add the Muhimbi **Merge documents** action. It has the following parameters: - **Source files name - 1** — You can hardcode the file name **MergeFile.PDF**. This file name should be the same as in previous steps. - **Source files content - 1** — The file content is the output of the **Get file content using path 2** action from earlier. - **Source files name - 2** — Enter **Name**, which is the output of the **List files in folder** action. - **Source files content - 2** — Enter **Body**, which is the output of the **Get file content using path** action.![file content](@/assets/guides/muhimbi/pdf-converter/power-automate/merge-documents-13.jpg) Add the OneDrive for Business **Create file 2** action. The action has three main parameters: - **Folder Path** — The path of your destination folder. - **File Name** — This is hardcoded to **MergeFile.PDF**. - **File Content** — This is **Processed files content**, which is the output of the **Merge document** action.![merge document action](@/assets/guides/muhimbi/pdf-converter/power-automate/merge-documents-14.jpg) Outside the **Condition 2** action, add a **Set variable** action. The action has two main parameters: - **Name** — Select the **Merged Count** variable from above. - **Value** — Set the **Value** field to **1**. You can test this workflow by setting the recurrence frequency to **Minute**. This will trigger the flow and merge multiple documents in the source folder into a single document in the target destination.![merge documents variable](@/assets/guides/muhimbi/pdf-converter/power-automate/merge-documents-15.jpg) ## Additional resources - [Error while merging existing PDF files](https://www.nutrient.io/guides/document-converter/sharepoint/troubleshooting/error-while-merging-existing-pdf-files-e-g-pdflexer-errors.md) --- ## Related pages - [Merge and combine PDF files using Power Automate](/guides/document-converter/power-automate/merge/merge-pdf.md) - [Merge PowerPoint files using Power Automate](/guides/document-converter/power-automate/merge/merge-ppt.md) - [Merge Word documents with Power Automate](/guides/document-converter/power-automate/merge/merge-word.md) - [Merge documents with low-code solutions](/guides/document-converter/power-automate/merge.md)
