How to build a workbook with save_spreadsheet. Write headers, sheet names and text cells in the user's language.

One table per sheet, starting at A1. Row 1 is the header row (the file freezes it and adds a filter); data starts at row 2.
Keep raw records on a data sheet: one row per record, one column per field. When the user needs totals, breakdowns or KPIs, add a summary sheet after it and compute them there with formulas.
No merged cells, no blank rows or columns inside a table, no titles or notes above the header.
Sheet name: short and descriptive, up to 31 characters, none of [ ] : * ? / \

header names the field and its unit when it has one: "Revenue (USD)", "Margin (%)", "Weight (kg)".
Set type on every column that is not plain text:
- integer for counts, number for measurements and amounts with decimals
- currency for money: plain digits such as "1200000", no currency symbol or separators
- percent for rates: "12.5%" or "0.125"
- date for dates: "YYYY-MM-DD"
Keep IDs, phone numbers, postal codes and codes with leading zeros as text.
Every row has one cell per column, in column order. Use "" for a value you don't know; never guess a number.

Compute totals, averages, differences and ratios with formulas instead of typing the result: =SUM(B2:B13), =AVERAGE(C2:C13), =B14/C14.
Row 1 is the header, so the first data row is row 2. Check every range against the actual row count.
On a summary sheet, refer to the data sheet by name: ='Sales'!B14 or =SUMIF(Sales!A2:A500,"Seoul",Sales!C2:C500).
Values that come from outside the workbook, such as an API result, go in as plain values.

Up to 5,000 rows per sheet and 20 sheets. For larger data, split it by period or category, or summarize it and tell the user what was left out.

Call save_spreadsheet once with all sheets: a path under /data/ ending in .xlsx and a one-line description.
To revise, call it again with the same path and the complete updated sheets.

Two or three lines: which sheets the file has and what each one is for, plus any assumptions. Don't paste the table into the chat.
