The Scenario
Your agency just revised its retainer pricing. Three new service tiers, each with updated rates. You have 12 draft proposals sitting in Nusii that all need those line items added before you send them out next week. The proposals exist, the sections exist, the pricing workbook is right in front of you. What's missing is the hour it would take to open each proposal and add the items one at a time.
The bad version:
- Open Nusii, find proposal 1, go to the section, click Add Line Item, type the item name, enter the price, enter the quantity, save. Repeat for the second item. Repeat for the third.
- Open the next proposal. Repeat everything.
- Twelve proposals, three items each — thirty-six manual line-item additions. Miss one and the proposal goes out with incorrect pricing.
This is the kind of task that sounds quick until you're in the middle of it. The cognitive overhead of keeping track of which proposals got which items, across thirty-six separate UI interactions, is its own tax.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Excel workbook. It reads the proposal IDs, section IDs, and line-item details from your worksheet and adds every line item to every proposal in one operation through the Nusii integration.
Here is the prompt for this specific task:
Read my Excel line-item additions sheet (Proposal ID, Section ID, Item Name, Unit Price, Quantity) and bulk-add every line item to the correct Nusii proposal section
What You Get
- One line item added per row, to the exact proposal and section specified.
- If the operation succeeds, a confirmation note is written back into the Result column.
- If a proposal ID or section ID is invalid, an error note lands in the Result column instead of silently skipping.
- All 36 additions happen in sequence — no manual clicking between proposals.
What If the Data Is Not Quite Ready
The same three line items need to go into every proposal, not unique items per row
For every proposal ID in the Proposal ID column, add three line items to the Section ID column value: the first using the name, price, and quantity from the first reference row; the second from the second; the third from the third — write "Done" in the Result column for each proposal that completes
Some proposals already have these line items and should be skipped
For each proposal ID in the workbook, check whether a line item named exactly as in the Item Name column already exists in the specified section — if it does, write "Already exists" in the Result column and skip — if it does not, add the line item and write "Added" in the Result column
Unit prices need to be converted from the old rate before adding
For every row in this workbook, multiply the Unit Price column by 1.15 to apply the revised rate — then create a line item in the Nusii proposal from Proposal ID, section from Section ID, with the Item Name, the adjusted price, and the Quantity value
Full pricing update: dedup, add, and confirm in one pass
Check the Proposal ID column for duplicates — if any appear more than once, note "Duplicate row" in the Result column and skip extras — then for each unique proposal ID, add a line item using Section ID, Item Name, Unit Price, and Quantity — write "Added" in Result on success, write the error message on failure
Specifying the dedup and the add in one prompt means SheetXAI handles the logic before a single API call is made.
