The Scenario
You are a project coordinator at a consulting firm. You just got back from a ten-day client site visit and you have 35 expense rows sitting in a Google Sheet.
Date, amount, category, project ID, notes — all filled in during the trip, because you knew this moment was coming. The problem is that every one of those rows needs to be created as a Harvest expense record before the reimbursement cycle closes on Friday.
Entering them one at a time in Harvest means: click Expenses, New Expense, select project, enter amount, pick category, add notes, set date, save. Thirty-five times. At two minutes per entry, that is over an hour of data entry before you can submit for reimbursement.
The bad version of Thursday morning:
- Open Harvest, click to create a new expense
- Look at row one in the sheet, type in the project, amount, category, and notes
- Move to row two, realize you forgot to enter the date on row one, go back
- Make it through twenty rows before losing track of which row you are on
- Submit the wrong amount on row thirty-one because you are tired.
The fast version is one prompt.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your spreadsheet that reads every expense row and creates each Harvest record in one pass, skipping any rows that are missing required data.
Open the SheetXAI sidebar and type:
Create a Harvest expense for every row in my Trip Expenses sheet. Columns are Date, ProjectID, ExpenseCategoryID, TotalCost, and Notes. Skip any row where TotalCost is blank and write "SKIPPED" in column F for those rows. For successfully created rows, write the Harvest expense ID into column F.
SheetXAI reads all thirty-five rows, creates each expense record in Harvest with the right project, category, amount, and notes, and writes the expense ID or skip reason into column F. When you submit the reimbursement request, every Harvest record is already there.
What You Get
Thirty-five expense records created in Harvest:
- Correct project assignment — each expense linked to the right project ID from column C
- Correct category — from the expense category ID in column D
- Date and amount — written exactly as they appear in the sheet
- Notes preserved — so the client context stays attached to each expense in Harvest
- Expense ID written back into column F — for your reimbursement records
The IDs in column F make the reimbursement audit clean. If anyone questions a specific expense, you have the Harvest expense ID to look it up directly.
Missing a few expense category IDs? Tell SheetXAI which column has the category name and it can look up the IDs from Harvest's category list before creating the entries.
What If the Data Is Not Quite Ready
Post-trip expense sheets are almost never clean. SheetXAI handles the data issues and the Harvest entry in the same prompt.
When expense category names are in the sheet instead of IDs
You typed "Travel," "Meals," and "Software" in column D, but Harvest's API expects numeric category IDs.
Look up my Harvest expense categories and map the category name in column D to the correct Harvest category ID. Then create a Harvest expense for each row using the mapped category ID, the project ID in column C, total cost in column E, and date in column A. Write the expense ID into column F.
When some rows are personal expenses that should not go to the project
Column F has a "Type" field and a few rows are marked "Personal." Those should be skipped entirely.
Create Harvest expenses only for rows where column F says "Client." Skip rows where column F says "Personal" and write "PERSONAL — SKIPPED" in column G for those rows. For all others, write the Harvest expense ID into column G.
When expenses need to be split across two projects
A few rows are team dinners that should be split evenly between two project IDs listed in column C, separated by a slash.
For any row in column C that contains a slash, split the TotalCost in column E evenly between the two project IDs and create one Harvest expense for each project. Write both returned IDs into column F separated by a comma.
When you are doing this for three team members at once
The sheet has a TeamMember column and expenses from three different people who were all on the same site visit, each needing their expenses created under their own Harvest user.
For each row, look up the Harvest user ID matching the name in column B, then create a Harvest expense for that user using the project ID in column C, category in column D, amount in column E, date in column A, and notes in column F. Write the Harvest expense ID and the user ID into columns G and H.
The pattern: the sheet is the expense ledger. SheetXAI reads it, creates every Harvest record in one pass, and writes the IDs back so you have a complete paper trail without clicking through Harvest's UI thirty-five times.
