Sheet-to-Doc Image Processing: How to Insert Dynamic Images in Word

In the process of automated document generation, image processing is an important feature. Sheet-to-Doc provides powerful image processing capabilities, allowing you to dynamically insert images into Word documents based on Excel data. Today, I will detailedly introduce Sheet-to-Doc’s image processing functionality to help you master how to insert dynamic images in Word and create richer, more professional automated documents.

What are Image Placeholders?

Image placeholders are a special type of placeholder in Sheet-to-Doc, used to mark image positions in Word templates. When generating documents, the tool will replace these placeholders with actual image files. The basic syntax of image placeholders is {@image column name | _inline_image} or {@image column name | _block_image}, where “image column name” is the column name in Excel tables that stores image names or paths.

Basic Usage Method of Image Placeholders

Step 1: Prepare Excel Data

Add a column in Excel table to store image names or paths. For example, you can add a column named “Product Image” to store product image file names.

Product ID Product Name Product Image
P001 Product A product-a.png
P002 Product B product-b.png
P003 Product C product-c.png

Step 2: Prepare Word Template

Add image placeholders in Word template using the format {@image column name | _inline_image} or {@image column name | _block_image}. For example:

1
2
3
4
5
6
Product Details

Product ID: {Product ID}
Product Name: {Product Name}
Product Image:
{@Product Image | _inline_image}

Step 3: Upload Image Files

In the Sheet-to-Doc tool, upload all image files that need to be inserted into the documents. You can upload multiple image files at once or one by one.

Step 4: Generate Documents

Click the “Generate” button, and the tool will automatically match the image names in Excel data with the uploaded image files, inserting the images into the specified positions in the Word documents.

Best Practices for Using Image Placeholders

1. Uniform Image Formats

It is recommended to use uniform image formats, such as PNG or JPG, for easy management and processing.

2. Use Clear Image Names

Choose concise and clear image names, preferably consistent with product IDs or names in Excel data for easy matching and management.

3. Optimize Image Sizes

Before uploading images, it is recommended to optimize image sizes to avoid using oversized image files, which can affect document generation speed and document size.

4. Test Image Placeholders

Before generating a large number of documents, test image placeholders with a small amount of data to ensure that images can be correctly inserted into documents.

5. Pre-adjust Image Placeholder Sizes

Pre-adjust the sizes and positions of image placeholders in Word templates to ensure that generated images meet expected effects.

6. Backup Image Files

It is recommended to backup all image files that need to be inserted into documents to avoid missing images in generated documents due to image file loss.

Common Problems and Solutions for Image Processing

Problem 1: Images Cannot Be Inserted Correctly

Reason: Image names in Excel data do not match uploaded image file names, or image file formats are not supported.

Solution:

  • Check whether image names in Excel data are completely consistent with uploaded image file names, including case and file extensions
  • Ensure that uploaded image file formats are supported (PNG, JPG, JPEG, GIF, etc.)
  • Re-upload image files

Problem 2: Generated Image Sizes Do Not Meet Expectations

Reason: Image placeholder sizes in Word templates are not pre-adjusted, or the images themselves are too large.

Solution:

  • Pre-adjust the sizes and positions of image placeholders in Word templates
  • Optimize the sizes and dimensions of uploaded image files
  • Regenerate documents

Problem 3: Images Missing from Generated Documents

Reason: Image names in Excel data do not exist in uploaded image files, or image files failed to upload.

Solution:

  • Check whether image names in Excel data are correct
  • Ensure that all required image files have been successfully uploaded
  • Re-upload missing image files

Problem 4: Slow Document Generation Speed

Reason: Uploaded image files are too large, or there are too many images.

Solution:

  • Optimize the sizes of uploaded image files
  • Reduce the number of documents generated at a time
  • Generate documents in batches
