# Your spreadsheet - Google Sheets or Excel

> The spreadsheet ReceiptFold writes - where it lives, its tabs and columns, what you can edit, and the only file ReceiptFold can touch.

Every receipt becomes a row in **one spreadsheet you own**: a Google Sheet in your Google Drive, or an Excel workbook in your OneDrive (folder `Apps/ReceiptFold`). ReceiptFold creates the file when you connect storage and **only ever touches that file**. The kept PDFs and pictures of your receipts are stored in your drive too, and each row links to its own.

## Tabs and columns

The main tab is **invoices**: one row per receipt, payment or income.

| Column | What it holds |
| --- | --- |
| `invoice_date` | The date on the receipt |
| `received_at` | When the message reached ReceiptFold |
| `source` | Which source (forwarding address) it came from |
| `vendor_id`, `vendor_name` | Who you paid, recognised from the sender and the content |
| `invoice_number` | The receipt or invoice number, when there is one |
| `period_start`, `period_end` | The period a subscription charge covers |
| `amount`, `currency` | The amount in its own currency |
| `amount_base`, `base_currency`, `fx_rate`, `fx_date` | The amount converted to your base currency, with the rate used |
| `category` | The category (built-in or one you created) |
| `kind` | Expense, income or refund |
| `paid_via` | The bank or card that sent a payment notice, when the receipt came through one |
| `status`, `confidence`, `parser` | How the row was read and how sure the reading was |
| `attachment_url` | The link to the kept PDF or picture in your drive |
| `notes` | Your own notes |

Other tabs: **invoice_lines** (what was bought, one line per item, when the receipt says it), **vendors** (each vendor with its category and how it is recognised), **sources** (your forwarding addresses), and three working tabs that start with an underscore (`_review`, `_index`, `_meta`) that ReceiptFold uses for the review queue, to skip duplicates and to remember your settings, budgets, notes and conversation. Leave the underscore tabs as they are.

## Editing

The file is yours: you can sort, filter, add your own columns, chart it or share it. ReceiptFold keeps your extra columns. Changes you make in the app (a category, a vendor rule, a note, a confirmed review) are written back to the file.

## Duplicates

Each receipt is recognised by its content, so the same receipt forwarded twice, or imported and forwarded, is written once.

## Access and disconnecting

- Google: ReceiptFold uses the `drive.file` scope, so it can only see files it creates or that you pick. It cannot read the rest of your Drive.
- Microsoft: ReceiptFold uses OneDrive's app folder (`Apps/ReceiptFold`) and cannot see the rest of your OneDrive.
- Deleting a workspace (Settings → Workspace) deletes ReceiptFold's records and revokes its access at the provider. Your file stays in your account.
