Mammoth vs Excel + AI
A brilliant answer once, or the same answer every week.
Excel with an AI assistant is useful, and for a one-off question it is often the fastest thing available. The problem is durability. The file is a snapshot the moment it's saved. The formulas live in one person's copy. Next month someone repeats the whole exercise by hand, usually with slightly different results. Mammoth is for the reports that have to be right again next week without anyone rebuilding them.
Side by side
The same nine criteria we use on every comparison
Including the two where the answer doesn't favour us.
| Mammoth | Excel + AI | |
|---|---|---|
| Time to first trustworthy dashboard | Around 15 minutes from raw data | An hour, and then it's a file, not a dashboard |
| Who can build one | Anyone on the team, in plain language | Anyone. That's the appeal |
| Data preparation | Recorded steps that re-run on new data | Manual, and repeated from scratch each time |
| Cost to share with 200 viewers | $0, from a single source of truth | $0, as 200 copies that drift apart |
| Keeping numbers current | Scheduled and event-driven refresh, built in | Someone redoes the work |
| Data volume | 1B+ rows on a single canvas | Roughly a million rows before it struggles |
| Audit trail | Activity log and restorable checkpoints | Version history on the file, if you're lucky |
| Compliance | SOC 2 Type II, ISO/IEC 27001:2022, HIPAA, GDPR | Whatever the tenant holds. The file itself carries nothing |
| Ad-hoc flexibility | Good, within the pipeline model | Higher. A blank grid does anything |

Fair's fair
What Excel + AI does better
No comparison is worth reading if it pretends the other tool has no advantages. These are real.
- Everyone already has it and already knows it
- Unbeatable for ad-hoc calculation and quick modelling
- No procurement, no rollout, no training
- Complete flexibility for one-off analysis
So which should you pick?
Genuinely depends on the job. Here's how we'd decide.
Choose Excel + AI if…
- It's a one-off question you won't ask again
- The dataset is small and lives in one place already
- You need to model scenarios by hand, cell by cell
Choose Mammoth if…
- The same report gets rebuilt every week or month
- Numbers disagree because several copies of the file exist
- The data is bigger or messier than a sheet handles well
