Variable Images From CSV
Script for Adobe Photoshop
Latest update 3/28/2023, version 3.0
The script reads a CSV spreadsheet of multiple image names and text, and for each row of data, updates layer names that match column heads to the image or text specified. Then each unique result is output in the selected file format. Simplify data-driven graphics in Photoshop with batch processing and variable data sets rolled into one solution.
- Combine images and text for personalized images
- Update any number of image and text layers
- Specify URLs to download image and import to layer
- Output formats BMP, JPG, PNG, PSD, or TIF
- An easier way to accomplish data merge in Photoshop
- Recognizes column for output file name

NOTE: after video production, the feature Image placement was added in response to user feedback. See instructions below for details.
Before using the script
Using the script requires some preparation. First is a template image with specific layer names.
This example is two normal pixel layers, “image1” and “image2”, then three text layers, “text1”, “text2”, and “text3”. And one final normal pixel layer “logo”. Pixel layers may be masked as are layers “image2” and “logo” in this example.
The number of layers to update is limited only by the resources available to Photoshop. Layers may exist that are not updated. For example, elements common to all images output. Any layer name that does not appear in the spreadsheet is untouched and, if visible, is included with all images output.
The second item to prepare is a spreadsheet of image file names and text. The column heads must match layer names in the template image. This tells the script what goes where. If column heads exist that have no matching layer in the template image, the columns are ignored.
In this example, rows of the column “image1” are image file names to import and update the layer named “image1” of the template image. Rows of the column “text1” replace the text contents of the layer named “text1”.
And so on with all layer names and column heads present in both the template and data.
Columns for images may be the full path to the file, a URL to download the file, or the file name only. If file name only, select the folder to search for images in the section Images. It is possible to mix image names that are full paths and/or URLs with images that are file name only. See the section Further reading for more details.
There is one special column head that is optional and not related to any layer name. Use the column head “file name” to indicate the output file name. If this column is absent, the first image name or text value found is used to name the output file.
Once the spreadsheet is ready, save it as Comma Separated Values (CSV format). From Excel, choose Save As, and in the drop-down list Save as type, select CSV UTF-8 Comma delimited. UTF-8 is recommended so any Unicode characters are preserved.
How to use the script
With the template image open, run the script.
The interface has three sections: Data file, Images, and Output. Select the data file, optionally an images folder, and the output folder. Enable the desired options and click the OK button to begin. If any problems occur, a log file is written in the output folder, and the user is notified.
Section 1: Data file (CSV)
Delimiter — the character that separates columns of the data file. The default is comma, normal in the United States. Some European countries use semicolon rather than comma. Select the delimiter used in your region of the world.
File — select the CSV data file.
Section 2: Images
Data for images is full path or URL (or there are no images) — when image columns in the data are full paths to images or URLs, there is no need to select a folder where they are located. Likewise, if the data is only text to update, a location to search for images is irrelevant. In these cases, choose this option, and the button Folder is disabled.
Data for images is the file name only, located in folder below — without a full path to images, the location to search for them is needed. Use the button Folder to select a location.
Folder — select a folder to search for images. The script processes each image file in the spreadsheet data that matches a file found in this folder.
Image placement — determines how imported images are scaled. All images are first centered relative to the canvas or layer mask, if one is applied to the layer. Fill then scales the image so its shortest dimension reaches the canvas or mask boundary and crops out any portion that exceeds the boundary. Fit scales the image so its longest dimension reaches the canvas or mask boundary and none of the image is cropped. The options Fill and Fit maintain proportions. The option Stretch scales images non-proportionally so that both dimensions fit the canvas or mask. For imported images that match the aspect ratio of the canvas or mask, the image is scaled to precisely the canvas or mask size, and these options have no effect.
Section 3: Output
Folder — select the location to which images are output.
Format — select the file format to output. Choices are BMP, JPG, PNG, PSD, or TIF.
Flatten — the result is a single “Background” layer. BMP and JPG always perform this step.
Single merged layer — applies to formats PNG, PSD, and TIF. When enabled, hidden layers are discarded, and the remaining layers are merged to a single layer. If a layer mask remains, it is applied. PNG does not support multiple layers, so this step always occurs if not flattened. The option does not apply to BMP or JPG as both do not support transparency and must be flattened.
The options Flatten and Single merged layer are mutually exclusive. Choose one or the other, or neither. The script does not allow both.
Quality — applies to JPG format only. Valid range is from 0 to 12. 0 is extreme compression resulting in low quality. 12 is light compression that is virtually indistinguishable from the original, the highest possible quality, which of course, results in the largest file size. 10 to 12 is recommended for print or other high-quality reproduction. For web images, 5 to 8 is an acceptable range.
Convert to profile — converts color to the selected profile prior to output. Note that BMP and PNG formats are always converted to sRGB web standard, and the option to select otherwise is disabled.
If you’ve reached this point, you know enough to use the script. The remainder is not crucial to read, but helps understand how the script works. This section is last, in the interest of minimizing “Too Long; Didn’t Read” (TL;DR).
Each image imported is centered relative to the target layer then scaled based on the option Image placement. If set to Fill and the layer is unmasked, the imported image shortest dimension is scaled to match the canvas size and excess image is cropped out. For layers that are masked, the imported image shortest dimension is scaled to fit inside the mask and excess image is masked to hide it. If set to Fit and the layer is unmasked, the imported image longest dimension is scaled to match the canvas size and none of the image is cropped. For layers that are masked, the imported image longest dimension is scaled to fit inside the mask, and because none of the image is masked, all of the image appears. The option Stretch scales images non-proportionally so that both dimensions fit the canvas or mask. All image layers are converted to smart objects, then the layer contents are updated. If the layer is a normal pixel layer and effects are applied, the effects are copied and pasted back to the layer after converted to a smart object. For layers already smart objects, any layer effects remain.
For text layers, the contents are replaced, and any layer effects remain. If the text content might span multiple lines, use a text area rather than single line to define the placeholder. Do this by dragging the cursor to define the text area rather than simply click, which limits text to a single line. Using a text area is preferred because it adapts to single or multiple lines of content as needed. Single line text placeholders do not.
At this time, the replacement of text on a path is unreliable due to a bug in Photoshop that shifts the path position when altered by ExtendScript.
Regarding image full path versus file name only. It is possible to mix full paths, URLs, and file names only in the data file. Use the option Data for images is the file name only, and select a folder to search for images. Images that are file name only work as expected. Images that are full paths of course fail once prefixed with the path to the images folder, but the script doesn't immediately give up. Instead, the script tests if a file exists without the images folder prefixed. If a file is found, the script uses it and adds an alert to the log file. Images that begin with http are considered URLs and are not altered. The image is downloaded to the output folder, imported into the template, then deleted.
It is the responsibility of the user to ensure column heads match the correct kind of layer in the template image. If a column for file names matches the name of a text layer, the text content is updated to the file name. If a column for text matches the name of a pixel layer, the script reports “File not found” in the log, unless somehow, however unlikely, the text matches the name of a file in the images folder.
Converting color requires the image is flattened or merged to a single layer because the possibility of adjustment layers, which cannot change color space and maintain faithful results. For this reason, when Convert to profile is enabled, the script ensures either Flatten or Single merged layer is enabled.
TIP: Converting to another profile is primarily to make CMYK separations for print, which of course is functionality the script provides. But as well, this option can convert duotones to RGB or CMYK, or convert these and other color spaces to grayscale (use the profile Dot Gain 20%).
The formats JPG, PSD, and TIF always embed color profiles. BMP and PNG never embed color profiles.
Available color profiles
For the option Convert to profile, the list of profiles from which to choose is compiled by searching known locations in the system for .icc/.icm files and extracting the profile name. This occurs each time the script is launched. The list should include most of the same profiles Photoshop displays in dialogs such as Color Settings, but it doesn’t match exactly. If a needed profile does not appear in the list, add the profile to a location both Photoshop and the script look for profiles (below), and relaunch the script.
By default the script language is US English, which does not require further download or configuration. To have the script interface display other languages, choose from the available languages below. Download and copy the .i18n file to the script folder alongside the script. When launched, the script detects the language file and displays interface text in that language. If your language is not listed, download the English file and translate it. The file is plain text formatted as JSON, containing interface text in English, and a second value for its translation, which for the English file is the identical text. Copy the file and rename it to replace “en” with the relevant code for your language, then edit the file to change each line’s second value to the translation in your language. For more detailed instructions of how to edit and install i18n files, see How to Localize Scripts.
