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 spreadsheet 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 Google Sheet. It reads the proposal IDs, section IDs, and line-item details from your sheet and adds every line item to every proposal in one operation through the Nusii integration.
Here is the prompt for this specific task:
For every proposal ID in column A of this sheet, create a line item in the section ID from column B using the name from column C, amount from column D, and quantity from column E
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 column F.
- If a proposal ID or section ID is invalid, an error note lands in column F 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 column A, add three line items to section ID from column B: the first using name, price, and quantity from row 2 of the reference sheet; the second from row 3; the third from row 4 — write "Done" in column C for each proposal that completes
Some proposals already have these line items and should be skipped
For each proposal ID in column A, check whether a line item named exactly as in column C already exists in section column B — if it does, write "Already exists" in column F and skip — if it does not, add the line item from columns C, D, and E and write "Added" in column F
Unit prices need to be converted from the old rate before adding
For every row in this sheet, multiply the value in column D by 1.15 to apply the revised rate — then create a line item in the Nusii proposal from column A, section from column B, with the name from column C, the adjusted price, and quantity from column E
Full pricing update: dedup, add, and confirm in one pass
Check column A for duplicate proposal IDs — if any appear more than once, note "Duplicate row" in column F and skip extras — then for each unique proposal ID, add a line item in section column B with name from column C, price from column D, quantity from column E — write "Added" in column F 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.
