Method 1: Python with gspread and a service account
The most reliable path is to scrape with an API, shape the result into rows, and write them with gspread authenticated by a Google service account. Set up auth once: in Google Cloud, create a service account, enable the Google Sheets API and Google Drive API, download the JSON key, then open your Sheet and share it (Editor) with the service account email found in that JSON. After that, gspread opens the spreadsheet by key and writes a 2D list in a single batched update() call, which is far faster and friendlier to API quotas than cell-by-cell writes.
- Batch, do not loop: build one list of rows and send it once; avoid a
update_cell()call per field. - Multiple tabs: use
worksheet()oradd_worksheet()to split datasets across sheets in the same workbook. - Append vs overwrite:
append_rows()adds to the bottom for incremental runs; clear then write for full refreshes. - Headers: write a header row first so downstream formulas and pivots have named columns.
Method 2: No-code with IMPORTDATA, IMPORTHTML, and Apps Script
If your data is already a public CSV or a plain HTML table, you can pull it into a cell with no code at all. =IMPORTDATA("https://example.com/data.csv") loads a public CSV or TSV; =IMPORTHTML("https://example.com/page","table",1) grabs the first HTML table on a page. These are great for simple, static feeds but they have real limits: they cannot run JavaScript, cannot send custom headers or handle browser verification, and a sheet is capped at roughly 50 IMPORT-family functions. For anything dynamic, write a Google Apps Script function that calls a scraping API with UrlFetchApp.fetch(), parses the JSON, and writes rows with getRange().setValues(). Bind that function to a time-driven trigger to refresh on a schedule directly inside Sheets.
Get clean data in first: handle JS and verification
Both methods only work if the scrape returns real data, and that is where most Sheets tutorials quietly fail. Power Query, IMPORTHTML, and a plain requests.get() all return an empty preview when a site renders its table with JavaScript or shows a browser verification interstitial. A scraping API solves this by rendering the page in a real browser and routing through residential proxies, then handing you the finished HTML or an autoparsed table. With Scrappey you send one POST, set autoparse: true to get structured rows back, and reuse a session so paginated requests share cookies. Loop through pages, collect rows into one list, and write that list to Google Sheets in a single batched call - one workbook, every page, no empty previews.
