=DEEPSEEK() — use DeepSeek in Google Sheets

=DEEPSEEK() runs DeepSeek models from a cell in Google Sheets. DeepSeek’s API pricing is among the lowest of any capable model, which makes it attractive for very large bulk runs on your own key.

Syntax

=DEEPSEEK(prompt, [value])
Parameter Required Description
prompt yes The instruction for DeepSeek.
value no Extra input appended to the prompt, usually a cell reference.

Requirements

Like =GROK(), this is a bring-your-own-key function:

  1. A User Pro or Business plan of GPT for Sheets.
  2. A DeepSeek API key from platform.deepseek.com.

Add it via Extensions → GPT for Sheets → Set Up API Key → DeepSeek. Requests are billed by DeepSeek on your key.

Model options

Model When to use
deepseek-chat (default) Writing, extraction, classification and everyday spreadsheet text tasks.
deepseek-reasoner Logic, math, planning and multi-step prompts — slower but more careful.

Examples

Summarize feedback in A2:

=DEEPSEEK("Summarize in one sentence, keep the customer's main complaint", A2)

Extract fields from messy text in A2:

=DEEPSEEK("Extract the email address. Return only the email or 'none'.", A2)

Bulk-translate descriptions in A2:

=DEEPSEEK("Translate to German, return only the translation", A2)

Tips

  • deepseek-chat covers most spreadsheet tasks; switch to deepseek-reasoner only when rows need multi-step logic — it is slower.
  • For bulk runs, freeze results with Replace all GPT formulas with results when done.
  • No key and no paid plan? The built-in =GPT(), =CLAUDE(), =GEMINI() and =MISTRAL() need no configuration.
  • =GROK() — the other bring-your-own-key model function
  • =MISTRAL() — built-in fast, low-cost option
  • =GPT() — built-in default
