2 things to look at

no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
13 stars13 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its file declares

Drive live Excel workbooks via the Microsoft Graph workbook API with curl + jq. The user's OAuth bearer token is in $MICROSOFT_EXCEL_TOKEN; every call needs Authorization: Bearer $MICROSOFT_EXCEL_TOKEN. Base URL: https://graph.microsoft.com/v1.0. The workbook API operates on a drive item (an .xlsx in OneDrive/SharePoint), so you need its ITEM_ID.

Failures are {"error":{"code","message"}} — show message verbatim. 401 = token expired (re-install). 403 on a write = the user granted read-only.

G="https://graph.microsoft.com/v1.0"; AUTH="Authorization: Bearer $MICROSOFT_EXCEL_TOKEN"
# Find the workbook by name (then take .id as ITEM_ID)
curl -sS -H "$AUTH" "$G/me/drive/root/search(q='budget.xlsx')" \
  | jq '.value[] | {id, name, webUrl}'
# Worksheets in the workbook
curl -sS -H "$AUTH" "$G/me/drive/items/ITEM_ID/workbook/worksheets" \
  | jq '.value[] | {id, name, position}'

Read & write ranges

ITEM="ITEM_ID"; WS="Sheet1"
# Used range (values + formulas + formats)
curl -sS -H "$AUTH" \
  "$G/me/drive/items/$ITEM/workbook/worksheets/$WS/usedRange" \
  | jq '{address, values: .values}'

# Read a specific range
curl -sS -H "$AUTH" \
  "$G/me/drive/items/$ITEM/workbook/worksheets/$WS/range(address='A1:C5')" | jq '.values'

# Update a range (confirm first). values is a 2-D array matching the address shape.
curl -sS -X PATCH -H "$AUTH" -H "Content-Type: application/json" \
  -d '{"values":[["Q3",1200],["Q4",1580]]}' \
  "$G/me/drive/items/$ITEM/workbook/worksheets/$WS/range(address='A2:B3')" | jq '.address'

Append a row to a table

curl -sS -X POST -H "$AUTH" -H "Content-Type: application/json" \
  -d '{"values":[["2026-06-21","Acme",4200]]}' \
  "$G/me/drive/items/$ITEM/workbook/tables/Table1/rows/add" | jq '.index'

Gotchas

This is for cloud workbooks (OneDrive/SharePoint). A local .xlsx the user uploaded into chat is a different job (parse the file directly), not this skill.
Range address is a string like Sheet1!A1:C5 or just A1:C5 when scoped to a worksheet; values must be a 2-D array matching its dimensions.
For long-running edits Graph supports a workbook session header (workbook-session-id); for a few cells the default sessionless mode is fine.
