Setup

This skill requires the Rube MCP server connected at

https://rube.app/mcp

Before executing any tools, ensure an active connection exists for the

excel

(and optionally

googlesheets

) toolkit. If no connection is active, initiate one via

RUBE_MANAGE_CONNECTIONS

Core Workflows

to generate a new

.xlsx

file and upload it to OneDrive.

Tool:

EXCEL_CREATE_WORKBOOK

Steps:

Call
```

3. Upsert Rows by Key Column

Use

GOOGLESHEETS_UPSERT_ROWS

Key Parameters:

```
spreadsheetId
```
(required) -- The spreadsheet ID
```
sheetName
```
(required) -- Tab name
```
rows
```
(required) -- 2D array of data rows (min 1 row). If
```
headers
```
is omitted, the first row is treated as headers
```
headers
```
-- Column names for the data, e.g.,
```
["Email","Phone","Status"]
```
```
keyColumn
```
-- Column header to match on, e.g.,
```
"Email"
```
,
```
"SKU"
```
,
```
"Lead ID"
```
```
strictMode
```
--
```
true
```
(default) errors on mismatched columns;
```
false
```
truncates silently

Example:

Tool: GOOGLESHEETS_UPSERT_ROWS
Arguments:
  spreadsheetId: "1BxiMVs0XRA5nFMdKvBdBZjgmUUqptlbs74OgvE2upms"
  sheetName: "Contacts"
  keyColumn: "Email"
  headers: ["Email","Phone","Status"]
  rows: [["john@example.com","555-0101","Active"],["jane@example.com","555-0102","Pending"]]

4. Format Cells

Use

GOOGLESHEETS_FORMAT_CELL

to apply bold, italic, font size, and background colors to ranges.

Tool:

GOOGLESHEETS_FORMAT_CELL

Key Parameters:

```
spreadsheet_id
```
(required) -- The spreadsheet ID
```
range
```
-- Cell range in A1 notation, e.g.,
```
"A1:D1"
```
,
```
"B2:B10"
```
(recommended over index-based)
```
sheet_name
```
-- Worksheet name, e.g.,
```
"Sheet1"
```
```
bold
```
--
```
true
```
/
```
false
```
```
italic
```
--
```
true
```
/
```
false
```
```
fontSize
```
-- Font size in points, e.g.,
```
12
```
```
red
```
,
```
green
```
,
```
blue
```
-- Background color components (0.0--1.0 float scale, NOT 0--255)

Example (bold header row with blue background):

Tool: GOOGLESHEETS_FORMAT_CELL
Arguments:
  spreadsheet_id: "1BxiMVs0XRA5nFMdKvBdBZjgmUUqptlbs74OgvE2upms"
  range: "A1:D1"
  sheet_name: "Sheet1"
  bold: true
  fontSize: 12
  red: 0.2
  green: 0.4

5. Add New Worksheet Tabs

Use

GOOGLESHEETS_ADD_SHEET

to create new tabs within an existing spreadsheet.

Tool:

GOOGLESHEETS_ADD_SHEET

Key Parameters:

```
spreadsheetId
```
(required) -- The spreadsheet ID
```
title
```
-- Name for the new tab, e.g.,

```
GOOGLESHEETS_BATCH_GET
```
with the spreadsheet ID and target ranges
Validate headers and data alignment

Supporting Tools:

```
GOOGLESHEETS_GET_SHEET_NAMES
```
-- List all tab names in a spreadsheet
```
GOOGLESHEETS_GET_SPREADSHEET_INFO
```
-- Get metadata (sheet IDs, properties)
```
GOOGLESHEETS_FIND_WORKSHEET_BY_TITLE
```
-- Check if a specific tab exists

Recommended Execution Plan

Create or locate the spreadsheet using
```
GOOGLESHEETS_CREATE_GOOGLE_SHEET1
```
or reuse an existing
```
spreadsheetId
```

Confirm the destination tab using

GOOGLESHEETS_GET_SHEET_NAMES

GOOGLESHEETS_FIND_WORKSHEET_BY_TITLE

; create it with

GOOGLESHEETS_ADD_SHEET

if missing

Read existing headers (optional) using
```
GOOGLESHEETS_BATCH_GET
```
to align columns

Write or upsert data using

GOOGLESHEETS_BATCH_UPDATE

GOOGLESHEETS_UPSERT_ROWS

Apply formatting (optional) using
```
GOOGLESHEETS_FORMAT_CELL
```
Verify results (optional) using
```
GOOGLESHEETS_BATCH_GET
```
Fallback: If Google Sheets creation is blocked (HTTP 403), use
```
EXCEL_CREATE_WORKBOOK
```
for local
```
.xlsx
```
output

Known Pitfalls

Pitfall	Detail
HTTP 403 on sheet creation	`GOOGLESHEETS_CREATE_GOOGLE_SHEET1` fails when Drive create scope is missing. Reuse an existing `spreadsheetId` or fall back to `EXCEL_CREATE_WORKBOOK` .
Cell limit and rate throttling	Google Sheets has a ~5,000,000 cell limit per spreadsheet. Excessive write frequency triggers HTTP 429. Batch changes and chunk large writes (~500 rows/call).
Format range off-by-one	`GOOGLESHEETS_FORMAT_CELL` uses 0-based, endIndex-exclusive ranges when using index mode. Background color uses 0--1 float RGB, NOT 0--255 integer RGB.
Sheet title uniqueness	Sheet titles are not guaranteed unique across API responses. Prefer operating by numeric `sheetId` and verify the resolved tab before writing.
Upsert payload shape	`GOOGLESHEETS_UPSERT_ROWS` requires headers + 2D rows array. Sending list-of-dicts or empty `rows` causes validation errors. Ensure at least 1 data row.
