Import API data into Google Sheets — SheetSteps
QUICK ANSWER

Define the fields you need, call the API from a protected integration or Apps Script, validate the JSON response, flatten only the required properties and write one record per row. Never place reusable secrets in public cells or logs.

The useful version of this workflow is not a fragile formula that appears to work once. It is a repeatable process with explicit inputs, a known output schema and a visible status for every URL.

This guide shows how to turn a JSON API response into spreadsheet rows. It uses the actual SheetSteps AI flow: preview first, hosted extraction, a queued batch when the range is large, and confirmed write-back into Google Sheets.

INSTRUCTIONS

How to import public API data with SheetSteps AI

  1. 01
    Read the endpoint contract

    Identify authentication, pagination, rate limits and the exact JSON path containing records.

  2. 02
    Define the row schema

    Choose stable IDs and the small set of properties that belong in columns.

  3. 03
    Handle status codes

    Record 401, 403, 429 and server errors instead of treating every failure as an empty response.

  4. 04
    Inspect the preview

    Check the proposed columns, sample entries, extraction mode and destination before starting the job.

  5. 05
    Run and monitor the job

    Use the Jobs view to follow progress, pause or cancel the run, and inspect row-level failures.

  6. 06
    Confirm write-back

    Review the destination range and approve the write. Existing populated cells are not silently overwritten.

02
WEB SCRAPING

Map JSON to a deliberate spreadsheet schema

Nested API responses rarely belong in one cell. Choose a record array, preserve its stable ID and flatten only fields that users will filter, join or calculate.

Use null or blank consistently for missing entries. A stable schema makes refresh jobs and downstream formulas predictable.

03
WEB SCRAPING

Paginate without duplicating rows

Follow the API’s cursor or page token until it ends. Store the stable record ID and upsert by that ID rather than appending every response blindly.

Use idempotency for each page and record so a retry after a timeout cannot duplicate completed rows.

04
WEB SCRAPING

Keep API credentials out of spreadsheet cells

Cells are easy to share, copy and expose through formulas or screenshots. Store provider credentials encrypted, mask them in settings and never write them to logs.

SheetSteps provider connections are testable and deletable. Scraping usage and AI execution mode remain separate so users can understand which service handled each step.

  • Encrypt reusable credentials
  • Mask settings entries
  • Never log secrets
  • Validate response schema
  • Respect 429 retry guidance

COMMON QUESTIONS

Questions people ask

Can Google Sheets import JSON natively?＋

There is no general built-in IMPORTJSON function. Use Apps Script, an add-on or a protected backend integration.

How do I prevent duplicate API rows?＋

Keep the API’s stable record ID and update or upsert by that ID instead of blindly appending.

Where should an API credential be stored?＋

Use encrypted application settings or an appropriate secret store, not an ordinary spreadsheet cell.
