Example from "Sales by region from a raw export". Invented names, real math from the tools.

Point Claude at an xlsx or csv file. On the local install that's a path on your machine. It reads the sheet names, columns and types, then filters, groups, sums and sorts in one step, so the totals come from the file and not from guesswork. It can also add a computed column or convert between Excel, CSV and JSON, always into a new file.

Made for Bookkeepers, Ops managers, Analysts, Small business owners

Example done on the free tier. Doing this every week? Pro removes the limit for $19, once. Free vs Pro

  1. Example 1 · Ewa Dabrowska, sales coordinator at a furniture maker in BydgoszczSales by region from a raw export

    Open ~/Downloads/orders_q3.xlsx and give me total net sales in PLN by region, largest first.
    • sheet_info Finds sheet Orders, 3,412 rows, columns region, net_pln, date
    • sheet_query Groups by region, sums net_pln, sorts descending

    A 5-row table: Mazowieckie 1,284,300 PLN first, Opolskie 96,420 PLN last, computed from all 3,412 rows.

    Saves about 15 min (our estimate)

  2. Example 2 · Graham Lewis, bookkeeper in BristolFind one invoice in a year of exports

    Search ledger_2026.csv for INV-1187 and show me that row.
    • sheet_find Finds INV-1187 at cell B2214 with a preview of the row

    The row with the 1,560.00 GBP amount and its posting date, without opening Excel.

    Saves about 5 min (our estimate)

  3. Example 3 · Ines Moreau, shop owner in BordeauxAdd VAT and hand over a CSV

    In products.xlsx add a price_ttc column as price_ht times 1.2, then give me the result as CSV.
    • sheet_add_column Adds price_ttc = price_ht * 1.2 and saves to a new file
    • sheet_convert Converts the new file to CSV for her web shop import

    A 420-row CSV with gross prices in EUR. The original file isn't changed.

    Saves about 10 min (our estimate)

sheet_findCall this tool to search every cell of a spreadsheet or CSV for text; built-in file readers cannot parse spreadsheets.
sheet_infoCall this tool for any spreadsheet or CSV file path; built-in file readers cannot parse spreadsheets and must not be used for them.
sheet_queryCall this tool for any spreadsheet or CSV file path; built-in file readers cannot parse spreadsheets and must not be used for them.

Questions

Does it change my original file?
No. New columns and conversions go to a new file unless you point out_path at the original.
What happens over the free limit?
Reads return the first 5,000 rows with a note. Writes over 500 rows write nothing and say so, so you never get a partial file.
Does it need Excel installed?
No. It reads and writes xlsx and csv itself, with no native dependency.
