HolySheets!

HolySheets! is a TypeScript/Node.js library that simplifies interaction with the Google Sheets API, offering a Prisma-like syntax for querying and manipulating spreadsheet data. It abstracts away complexities like A1 ranges, headers extraction, and batch operations, letting you focus on your data and application logic.

Key Features

• No more manual A1 ranges: The library manages Google Sheets ranges internally.
• CRUD-like Operations: Insert, find (single or multiple), update, clear, and delete records with ease.
• Flexible Querying: Use various filters (equals, not, in, gt, contains, etc.) for precise querying.
• Metadata and Error Handling: Optionally retrieve rich metadata about operations and handle errors gracefully.
• Typed and IntelliSense-friendly: Written in TypeScript, providing static typing and better developer experience.

Installation

You can install HolySheets! using npm:

npm install holysheets

CLI (Public Read)

HolySheets now includes a CLI focused on public read operations from Google Sheets.

You can run commands in both forms:

# implicit source (google-sheets is the default)
npx holysheets read find-many --sheet <sheet-name> --spreadsheet-id <ID>

# explicit source
npx holysheets google-sheets read find-many --sheet <sheet-name> --spreadsheet-id <ID>

Supported Commands

holysheets read find-many
holysheets read find-first
holysheets read describe

holysheets google-sheets read find-many
holysheets google-sheets read find-first
holysheets google-sheets read describe

Help

holysheets --help
holysheets read --help
holysheets read find-many --help
holysheets google-sheets read find-many --help

Common Flags

--config <path>
--spreadsheet-id <id>
--sheet <name>
--header-row <number>
--skip-sheet-validation
--format <json|csv|ndjson>
--output <path>
--pretty

Config precedence:

• CLI flags override config file values.
• Config file values override internal defaults.

Example config file:

{
  "defaults": {
    "spreadsheetId": "<ID>",
    "sheet": "<sheet-name>",
    "headerRow": 2,
    "skipSheetValidation": false
  }
}

--skip-sheet-validation is an escape hatch that disables pre-checking whether the sheet name exists in public metadata.
It can reduce one network call, but it may allow silent fallback behavior from Google endpoints when the sheet name is invalid.

Schema Input

You can provide schema in one (and only one) of these ways:

--schema-file <path>
--schema-json <json-string>

Or explicit repeatable flags:

--schema-field <name>
--schema-type <string|number|boolean|date>
--schema-nullable
--schema-alias <name>

Schema block grouping rule:

• Each --schema-field starts a new schema field definition.
• Following --schema-type, --schema-nullable, and --schema-alias apply to the latest field.

Example:

holysheets read find-many \
  --sheet <sheet-name> \
  --spreadsheet-id <ID> \
  --schema-field nome_estabelecimento --schema-type string \
  --schema-field rating --schema-type number \
  --schema-field visitado_em --schema-type date --schema-nullable

Filters (where)

--where-field <field>
--where-op <equals|not|in|notIn|lt|lte|gt|gte|contains|startsWith|endsWith|search>
--where-value <value>

Filter block grouping rule:

• Each --where-field starts a new filter block.
• Following --where-op and --where-value apply to the latest field.
• Multiple blocks are combined with AND.

Example:

holysheets read find-many \
  --sheet <sheet-name> \
  --spreadsheet-id <ID> \
  --where-field rating --where-op gte --where-value 4 \
  --where-field nome_estabelecimento --where-op contains --where-value bar

Select

--select is repeatable:

holysheets read find-many \
  --sheet <sheet-name> \
  --spreadsheet-id <ID> \
  --select nome_estabelecimento \
  --select rating

Omit

--omit is repeatable:

holysheets read find-many \
  --sheet <sheet-name> \
  --spreadsheet-id <ID> \
  --omit instagram \
  --omit endereco

--select and --omit cannot be used together in the same command.

Output and Formats

• --format controls serialization.
• --output controls destination.
• Without --output, data is printed to stdout.
• With --output, data is written to file.

Output behavior:

• find-many: json, csv, ndjson
• find-first: json, ndjson
• describe: json, ndjson

csv is intentionally supported only for find-many in this version.

Examples:

holysheets read find-many --sheet <sheet-name> --spreadsheet-id <ID> --format json --output ./out/data.json
holysheets read find-many --sheet <sheet-name> --spreadsheet-id <ID> --format csv --output ./out/data.csv

Describe Behavior

read describe is metadata-focused and does not return data rows. It does not accept --where-*, --select, or --omit.

It returns:

• source
• spreadsheetId
• sheet
• headerRow
• detected columns (index + name)
• resolved schema (when provided)

Example:

holysheets read describe --sheet <sheet-name> --spreadsheet-id <ID> --header-row 2

Typical JSON output:

{
  "source": "google-sheets",
  "spreadsheetId": "<ID>",
  "sheet": "<sheet-name>",
  "headerRow": 2,
  "columns": [
    { "index": 0, "name": "nome_estabelecimento" },
    { "index": 1, "name": "rating" }
  ],
  "schema": []
}

Authentication and Credentials

Before using HolySheets!, you need Google credentials (Service Account or OAuth2) with access to your target spreadsheet. For guidance, check the Getting Credentials documentation.

Quickstart Example

import HolySheets from 'holysheets'

interface User {
  name: string
  email: string
  age: number
}

const holySheets = new HolySheets({
  spreadsheetId: 'YOUR_SPREADSHEET_ID',
  auth: yourAuthClient // e.g. a JWT or OAuth2 client
})

// Select the target sheet for operations
const users = holySheets.base<User>('Users')

// Find multiple users named 'Joe'
const result = await users.findMany({
  where: {
    name: {
      contains: 'Joe'
    }
  }
})

console.log(result.data)

API Overview

All operations support an optional OperationConfigs parameter, currently allowing includeMetadata: boolean. When includeMetadata is true, the result includes operation metadata (such as operationId, duration, status, and affected ranges).

Example:

const result = await users.findFirst(
  {
    where: { email: '[email protected]' }
  },
  {
    includeMetadata: true
  }
)

console.log(result.data) // The record data
console.log(result.metadata) // Additional metadata about the operation

Base Method

const users = holySheets.base<User>('Users')

Select the sheet to operate on. Once selected, you can chain operations like findFirst, findMany, etc.

getSheetId

Retrieve the numeric Sheet ID of a given sheet title:

const sheetIdResult = await holySheets.getSheetId('Users', {
  includeMetadata: true
})
if (sheetIdResult.metadata?.status === 'success') {
  console.log('Sheet ID:', sheetIdResult.data)
}

insert

Insert multiple records at the end of the sheet:

await users.insert(
  {
    data: [
      { name: 'Alice', email: '[email protected]', age: 25 },
      { name: 'Bob', email: '[email protected]', age: 30 }
    ]
  },
  { includeMetadata: true }
)

findFirst

Retrieve the first matching record:

const user = await users.findFirst(
  {
    where: {
      email: '[email protected]'
    }
  },
  { includeMetadata: true }
)

console.log(user.data)

findMany

Retrieve all matching records:

const activeUsers = await users.findMany(
  {
    where: {
      status: 'active'
    }
  },
  { includeMetadata: true }
)

console.log(activeUsers.data)

updateFirst

Update the first matching record:

const updatedUser = await users.updateFirst(
  {
    where: { name: { equals: 'Alice' } },
    data: { age: 26 }
  },
  { includeMetadata: true }
)

console.log(updatedUser.data)

updateMany

Update all matching records:

const updatedUsers = await users.updateMany(
  {
    where: { status: 'active' },
    data: { status: 'inactive' }
  },
  { includeMetadata: true }
)

console.log(updatedUsers.data)

clearFirst

Clear values (set them empty) in the first matching row:

const clearedUser = await users.clearFirst(
  {
    where: { name: 'Bob' }
  },
  { includeMetadata: true }
)

console.log(clearedUser.data)

clearMany

Clear values in all matching rows:

const clearedUsers = await users.clearMany(
  {
    where: { age: { lt: 25 } }
  },
  { includeMetadata: true }
)

console.log(clearedUsers.data)

deleteFirst

Delete the first matching row:

const deletedUser = await users.deleteFirst(
  {
    where: { email: '[email protected]' }
  },
  { includeMetadata: true }
)

console.log(deletedUser.data)

deleteMany

Delete all matching rows:

const deletedUsers = await users.deleteMany(
  {
    where: { status: { equals: 'inactive' } }
  },
  { includeMetadata: true }
)

console.log(deletedUsers.data)

Filters and Conditions

The where clause accepts filters like equals, not, in, notIn, lt, lte, gt, gte, contains, search, startsWith, and endsWith.

Examples:

// Find users with age greater than 30
await users.findMany({ where: { age: { gt: 30 } } })

// Find users whose name starts with 'Jo'
await users.findMany({ where: { name: { startsWith: 'Jo' } } })

Metadata and Error Handling

By specifying { includeMetadata: true } in configs, you receive metadata detailing:

• operationType (e.g., 'insert', 'find', 'update', etc.)
• status ('success' or 'failure')
• recordsAffected
• ranges involved
• error message if any
• duration
• operationId

If includeMetadata is not set or false, only data is returned.
