# Excel Row Count

## Text Example

```txt


Help me generate an Excel row-count tool. The input is an Excel file path, and the output is JSON containing the total number of rows in the whole file plus the row count for each worksheet. Ignore the header row and any data rows where all columns are empty.
- Note
    - The tool must be able to handle very large Excel files without crashing due to insufficient memory.

Runtime Variables Runtime Variables Runtime variables are used to manage private information, so you never write sensitive data directly into tool code or expose it to the LLM. What Are Runtime Variables When a tool needs sensitive information (such as API keys, account passwords, etc.), prefer runtime variables. Never type sensitive information directly into a conversation with the AI. You can also use runtime variables as a general configuration feature, making it easy to share settings across tools. Usage Guide Configure Variables Open the app and go to Settings > Runtime Variables . Runtime variables On this page you can: Add new variables. Edit existing variables. Delete variables you no longer use. Use Them in a Conversation When talking with the LLM, simply tell the AI to use a certain variable. The tool automatically searches for and checks whether that variable exists. Help me build an email-sending tool that supports a subject line, body editing, and attachment upload. Note: get the email account, password, and related parameters from the email variable. Do not ask the user to enter them. User variables in chat Reference Variables When you reference a variable in a conversation, the AI automatically recognizes it and reads the corresponding value—no need to type sensitive information manually. Security note : runtime variables are stored locally. They are never uploaded to the cloud or sent to the LLM, which better protects your information.

examples/email_send Email Tool and Variables Email-sending tools usually involve sensitive information. Do not provide the email account, password, and similar details directly in a conversation with the AI. Instead, create the relevant variables in runtime variables first and configure the required parameters there. For variable configuration, see Runtime Variables. Text Examples Use an AI Conversation to Sort Out the Variable Fields Needed for Sending Email I want to build an email-sending tool. What information does an email usually need to be configured with? Which parts are suitable to store in variables, and which are better entered as parameters at runtime? For the ones stored as variables, how should the fields typically be named—especially the English naming? Use Variables to Generate the Email-Sending Tool Use the actual key you configured in "Runtime Variables" as the variable name. For example, you can use email, or a naming style that suits you better such as my company.email. Help me build a small email-sending tool. It should support entering a subject, editing the body, and uploading attachments. Note: get the email account, password, and related information from the email variable. Do not ask the user to enter them manually.

Prompt

examples/pdf_parse_and_send_mail Extract PDF Data and Send Email After you have generated the relevant tools, you can try chaining several of them together through an AI conversation to accomplish more complex tasks. Text Example Manually drag a file into the chat box. Enter the following AI conversation: Use the PDF data extraction tool to extract data from the PDF file, and use the email-sending tool to send the generated result file to the relevant people. Email subject: PDF data extraction result Email body: Please see the PDF data extraction result file in the attachment Recipients: zhangsan@example.com, lisi@example.com Notes First, make sure you have already generated the relevant tools. If the PDF file contains sensitive information, be sure not to let the tool output results directly as JSON; instead, require it to write the results to a file and send that file as an email attachment. This avoids exposing the PDF content to the AI model during the conversation. Make sure you have configured the account, password, and other sensitive information required by the email-sending tool, and set them up in runtime variables.

Notes

How to Describe a Tool How to Have the AI Build a Tool When writing a tool requirement, the point is not to "write a lot"—it is to describe the interface clearly. A good tool prompt usually only needs to answer 6 questions: What does this tool do What is the input What rules to process by What artifact to output What to return in the end Whether to print stage logs Note: documents like this can live in the examples directory; the page path can be index or any other path. Recommended Format Help me build a {tool name} tool. Goal: What task should this tool accomplish Input: What is the input, what type, is it required Processing rules: What to extract, transform, filter, or count Output: Whether to generate a file If a file is generated, specify its format and save location Return: Return JSON Or return the result file path Logging: Whether to print stage logs Constraints: Requirements for large-file handling, error handling, sensitive information, etc. The Difference Between "Output" and "Return" Output: the actual result the tool produces, such as a CSV file, an Excel file, or a piece of structured data Return: what the tool hands back directly when execution finishes, such as the result file path, or JSON Two common patterns: Output a file, and return the path to that file Do not generate a file, and return JSON directly Three Most Common Examples Output a File, Return the File Path Help me build a PDF information extraction tool. The input is a PDF file path. Extract the company name, contact person, phone number, and contract number. Output a CSV file saved in the same directory as the input file. For the return value, provide the full path to the generated CSV file. Please print stage logs for reading the PDF, extracting fields, and writing results. Do Not Generate a File, Return JSON Directly Help me build a web content statistics tool. The input is a web page URL. Extract the plain text of the page body and count characters, paragraphs, and links. Do not generate a file; return JSON directly. Return Both a File Path and Summary Information Help me build a CSV cleaning tool. The input is a CSV file path. Output a new, cleaned CSV file. The return value should include the result file path, the original row count, the cleaned row count, and the number of removed rows. Please print stage logs, but do not output raw sensitive content. A One-Line Reminder When results are large or contain sensitive information, prefer "output a file + return the file path" When results are small and have a fixed structure, prefer returning JSON directly Do not write accounts, passwords, or keys directly into the prompt—read them from runtime variables Self-Check After Writing If you can clearly answer these 5 questions, it is usually enough: What is the input How to process it What is the output What to return Whether logs are needed Further Reading Excel Row-Count Tool PDF Data Extraction Tool Web Content Extraction Tool Email Tool and Variables How to Have the AI Build a Tool Recommended Format The Difference Between "Output" and "Return" Three Most Common Examples 1.

What is Jelly Studio

Home What it can do Turn repetitive steps across spreadsheets, files, receipts, and exported data into tools Run tools locally under control, with explicit directory, network, and runtime variable permissions Let you start a task first, then review and verify the results Reuse existing tools and compose them into longer flows when needed

What it can do

Home What it does not do It is not an AI IDE; it does not center on coding or engineering collaboration It is not a general-purpose automation platform; it does not try to cover every scenario It is not an open extension marketplace; it does not focus on installing large amounts of external capabilities It is not a fully autonomous agent; by default a human still initiates and reviews

What it does not do

Home Where it fits Spreadsheet cleaning, formatting, and batch statistics Information extraction from PDFs, receipts, and exported files Data conversion, reconciliation, aggregation, and cross-checking Batch generation of standardized emails, reports, or result files Everyday business processing that needs "visible process, checkable results, verifiable execution"

Where it fits

Home Where it does not fit well Open-ended creation, highly subjective judgment, or tasks whose results are hard to verify Fully automated flows that require long autonomous planning, multi-system orchestration, and almost no human review Deep coding workflows aimed at developers Scenarios where an extension ecosystem and plugin marketplace are the top priority

Where it does not fit well

Home How it works Describe a clear, repetitive business action in natural language Let Jelly Studio generate or adjust the corresponding tool Configure the model, runtime variables, and execution permissions for the tool Run it manually and check the results Reuse stable steps repeatedly, and compose them into longer flows when needed

How it works

Home Why it suits business processing Controllable : directory, network, and subprocess permissions are configurable, reducing "black-box execution" Reviewable : you can see the run inputs, execution results, and error messages Reusable : a tool built once can run repeatedly, instead of being re-described each time Safer : sensitive information can be managed through runtime variables, without writing it directly into the conversation
