Try different models
Find out which model works best for your use case. You can try different models by selecting them in the model switcher.
The model selection applies to all bulk AI tool runs and all GPT function executions in the current workbook.
Provide additional instructions
You can improve response quality by providing specific instructions that help the AI more closely follow your requirements for tone, style, format, rules, target audience, context, consistency, and other aspects.
Define the instructions as Global instructions in the Model settings. The instructions apply to all bulk tools and GPT functions in the current workbook.
Global instructions apply to all bulk AI tool runs and all GPT function executions in the current workbook.
For example, to add instructions to follow SEO best practices:
You are writing copy for a retail website. Take SEO into account.
Adjust the creativity level
Adjust the level of creativity (accuracy vs. freedom) the AI is allowed in generating results. The higher the value, the greater the creativity.
For example:
-
If you're generating marketing content, set a high creativity level to generate more engaging and imaginative text.
-
If you're generating technical specifications, set a low creativity level to ensure the generated text is precise and factual.
-
If you need the AI to follow your instructions to the letter, set the creativity level to 0.
The creativity level applies to all bulk AI tool runs and all GPT function executions in the current workbook.
Use multiple variables in a custom prompt
You must define at least one column variable in a custom prompt for context, for example {{A}} or {{Bike specifications}}. To generate more accurate results, provide more context by using additional variables in the prompt.
You can insert variables to reference columns, cells, and ranges in the prompt:
| Variable | Description | Example |
|---|---|---|
Column | Reference a column to include row-specific information from an adjacent column. Column variables work like relative references and are highlighted in blue. To add a column variable, use the Insert variables menus above the prompt. You can add a variable either by column label or column letter. | |
Cell or range from the current sheet | Reference a specific cell or range to include the same content as context for each row. Cell and range variables work like absolute references and are highlighted in green. To add a cell or range variable, type it directly in the prompt. | |
Cell or range from another sheet | Reference a cell or a range from another sheet in the same spreadsheet. The content can be, for example, reference data or other shared information. | |
Use web search capabilities
To generate more up-to-date content, select a model with web search capabilities (indicated by the 🌐 icon in the model switcher). The available web search options vary depending on the model you select. Learn more about web search options.
Enable Show sources to write the source references in the column to the right of the results column. This helps you understand the origin of the content and assess its reliability.
Include images in a custom prompt
To include images in a custom prompt, select a vision model in the model switcher. Then, select the columns that contain image URLs so they can be attached to the prompt for each corresponding row. Learn more about vision options.
Translate
Use the Translate bulk AI tool to translate product catalogs, website copy, customer reviews, or any other content directly in Excel, and optimize your translations by adding specific instructions and a glossary to guide the AI in the process. For example, you can translate a list of product names for a shoe store into French.
Settings (Translate)
| Field | Description | Example | |
|---|---|---|---|
| Header row (optional) | If your column headers aren't in the first row, select the number of the row that contains the headers. The bulk tool will run on the rows below this one. |
|
| Translate each cell in column | Select the column that contains the text you want to translate. |
|
| From (optional) | Enter the source language, or leave the field empty if you want the AI to detect the source language for each cell. | Empty |
 | To | Enter the target language. |
|
 | Put results in column | Select the column to put the results in. Cells in this column won't be overwritten with the results if they contain text. |
|
 | Translation instructions (optional) | Enter specific instructions for the translation. | |

Provide additional instructions
You can improve translation quality by providing specific instructions that help the AI more closely follow your requirements for tone, style, format, rules, target audience, context, consistency, and other aspects.
You can define the following types of instructions for the AI:
Translation instructions are defined for the current bulk tool run.
Global instructions are defined in the Model settings and apply to all bulk tools and GPT functions in the current workbook.
If both bulk AI tool instructions and global instructions are defined, the AI uses both as a combined set of instructions. For consistent results, make sure both sets of instructions are aligned and do not contradict each other.
Global instructions apply to all bulk AI tool runs and all GPT function executions in the current workbook.
For example, to omit the global instructions and only define translation instructions:
Adjust the creativity level

-
If you're generating marketing content, set a high creativity level to generate more engaging and imaginative text.
-
If you're generating technical specifications, set a low creativity level to ensure the generated text is precise and factual.
-
If you need the AI to follow your instructions to the letter, set the creativity level to 0.
The creativity level applies to all bulk AI tool runs and all GPT function executions in the current workbook.
Set the source language for translations
The AI can automatically detect the source language for translations, but manually defining it helps if the source text contains short, ambiguous phrases, which can confuse the AI. For example, "Trainers" in British English means "Sports shoes", whereas in American English, it means "People who train others".
Create a glossary for translations
Glossaries ensure that translations are consistent, respect corporate terminology, and remain on-brand. If your glossary is in the current spreadsheet, you can import it by clicking Import from sheet.
Classify / Categorize
Use the Classify / Categorize bulk AI tool to classify your catalog items, press articles, customer reviews, social media comments, or any other text directly in Excel. The tool classifies the content of each cell into one of the categories you provide if a match is found; if not match is found, the tool fills in #N/A. For example, you can improve your lifecycle inventory management by classifying apparel products according to the activity they are used for.
Settings (Classify / Categorize)
| Field | Description | Example | |
|---|---|---|---|
| Header row (optional) | If your column headers aren't in the first row, select the number of the row that contains the headers. The bulk tool will run on the rows below this one. |
|
| Classify each cell in column | Select the column that contains the text you want to classify. |
|
| Into one of these categories | Enter the categories to classify the text into. If the categories are listed in the current document, you can import them by clicking Import from sheet. | |
| Put results in column | Select the column to put the results in. Cells in this column won't be overwritten with the results if they contain text. |

Set Creativity to 0
Ensure Creativity is set to 0. This helps the AI follow instructions more closely.
The creativity level applies to all bulk AI tool runs and all GPT function executions in the current workbook.
Use full path for categories
If your categories form a hierarchy, use the full path of each category instead of just its name. This helps avoid ambiguity and ensures that the classification is as precise as possible.
Using only category names can lead to ambiguity. For example, T-shirts and Tops could be considered as very largely overlapping categories. By specifying Casual/T-shirts and Workout/Tops, you provide a clear context, ensuring that the AI classifies the items accurately according to the intended category.
For example, instruct the AI to classify items according to these category paths:
Casual/T-shirts
Casual/Jeans
Workout/Tops
Workout/Bottoms/Shorts
Workout/Bottoms/Pants
Extract
Use the Extract bulk AI tool to extract key information like names, email addresses, and product attributes from unstructured text directly in Excel. For example, you can extract name, weight, and price from bike model descriptions to create a catalog.
Settings (Extract)

Remove irrelevant information | Define what should be excluded from the extraction to get cleaner results. | |
Normalize entities | Set a consistent output for variations of the same entity in your text. | |
Extract numerical values and units | Separate numbers from units to simplify their manipulation. | Add |
Perform open-ended extraction
Open-ended extraction helps you gather a wide range of information without specifying each entity. This approach works well when entities vary from one cell to another or when you want to avoid missing any extraction.
For example, enter the following in the Extract field:
All relevant product details as a comma-separated list.
Prompt images (Vision)
Use the Prompt images (Vision) bulk AI tool to generate content based on images directly in Excel. For example, you can generate descriptions for your product images to improve your listings.
