At the time of writing (2023 February 15), Airtable recommends Personal Access Tokens for interacting with the official API.

NodeJS Integration

The main module is airtable and can be installed with npm:

npm i --save https://cdn.sheetjs.com/xlsx-latest/xlsx-latest.tgz airtable

To obtain a reference to a table, code needs a PAT, the name of the workspace (typically starting with app), and the name of the desired table (the Excel import typically supports the worksheet name):

const Airtable = require("airtable"), XLSX = require("xlsx");
/* query all records in a table */
const conn = new Airtable({apiKey: "PAT...", /* and other options ... */});
const table = conn.base("app...").table("tablename...");

Exporting Data

When querying data, a result set will be a simple array of Record objects. The fields property is a simple JS object compatible with json_to_sheet:

/** Create SheetJS worksheet from Airtable table */
async function airtable_to_worksheet(table) {
  /* get all rows */
  const result = await table.select().all();

  /* pull raw objects from the result */
  // highlight-next-line
  const aoo = result.map(r => r.fields);

  /* create a worksheet */
  const worksheet = XLSX.utils.json_to_sheet(aoo);
  return worksheet;
}

:::caution

The results are not guaranteed to be sorted. The official API includes options for sorting by fields.

:::

Importing Data

When inserting records, each object should be wrapped in a parent object with a single fields property:

/** Append records from a SheetJS worksheet to Airtable table */
async function airtable_load_worksheet(table, worksheet) {
  /* suppose the field names */
  const aoo = XLSX.utils.sheet_to_json(worksheet);

  /* reshape to be compatible with Airtable API */
  // highlight-next-line
  const airtable_rows = aoo.map(fields => ({ fields }));

  /* upload data */
  return await table.create(airtable_rows);
}

Complete Example

0. Create a free Airtable account.

Personal Access Token

:::note

In the past, Airtable offered API keys. They are slated to deprecate API keys in January 2024. They recommend "Personal Access Tokens" for operations.

:::

API actions will require a PAT, which must be created through the developer hub:

1. Click on account icon (topright area of the page) and select "Developer Hub".

2. Click "Create Token".

3. In the form, make the following selections:

• Name: enter any name (for example, "SheetJS Test")
• Scopes: data.records:read and data.records:write (adding 2 scopes)
• Access: "All current and future bases in all current and future workspaces"

The form will look like the screenshot below:

4. Click "Create Token" and you will see a popup. Copy the token and save it.

Workspace

For the purposes of this demo, a sample workspace should be created:

5. Download https://sheetjs.com/pres.xlsx

6. Create a project in Airtable using "Quickly upload". Select "Microsoft Excel" and select the downloaded file from step 1. Click "Upload", then "Import".

7. A workspace will be created. The name will be found in the URL. For example:

https://airtable.com/appblahblah/tblblahblah/blahblah
--------------------/^^^^^^^^^^^/ workspace name

the first part after the .com will be the workspace name.

Exporting Data

8. Save the following to read.js:

const Airtable = require("airtable"), XLSX = require("xlsx");
// highlight-start
/* replace the value with the personal access token */
const apiKey = "pat...";
/* replace the value with the workspace name */
const base = "app...";
// highlight-end
(async() => {
  const conn = new Airtable({ apiKey });
  const table = conn.base(base).table("Sheet1");
  const result = await table.select().all();
  const aoo = result.map(r => r.fields);
  const ws = XLSX.utils.json_to_sheet(aoo);
  const wb = XLSX.utils.book_new();
  XLSX.utils.book_append_sheet(wb, ws, "Sheet1");
  XLSX.writeFile(wb, "SheetJSAirtable.xlsb");
})();

9. Replace the values in the highlighted lines with the PAT and workspace name.

10. Run node read.js. The script should write SheetJSAirtable.xlsb. The file can be opened in Excel.

Importing Data

11. Create a file SheetJSAirpend.xlsx with some new records in sheet Sheet1:

npx xlsx-cli SheetJSAirpend.xlsx should print the following data:

Sheet1
Name,Index
Someone Else,47

12. Save the following to write.js:

const Airtable = require("airtable"), XLSX = require("xlsx");
// highlight-start
/* replace the value with the personal access token */
const apiKey = "pat...";
/* replace the value with the workspace name */
const base = "app...";
// highlight-end
(async() => {
  const conn = new Airtable({ apiKey });
  const table = conn.base(base).table("Sheet1");
  const wb = XLSX.readFile("SheetJSAirpend.xlsx");
  const ws = wb.Sheets["Sheet1"];
  const aoo = XLSX.utils.sheet_to_json(ws);
  await table.create(aoo.map(fields => ({ fields })));
})();

13. Replace the values in the highlighted lines with the PAT and workspace name.

14. Run node write.js. Open Airtable and verify the new row:
