Kachink vs Spreadsheets
Spreadsheets give you total control. Kachink gives you total consistency. They optimize for different things — here's how to pick.

Where spreadsheets break down
Spreadsheets are powerful — that's not the issue. The issue is that power requires effort, and effort kills consistency. Most personal expense spreadsheets are abandoned within three months.
Data entry friction
Opening a spreadsheet, finding the right row, entering the amount, category, and date — it takes 30 seconds per transaction. That adds up to "I'll do it later" and later never comes.
Formula maintenance
SUMIFS, pivot tables, currency lookups — they work until you add a row in the wrong place, change a category name, or forget to update the exchange rate formula.
No mobile story
Google Sheets on mobile is usable. It's not pleasant. Logging a quick expense at a restaurant means zooming, scrolling, and typing into tiny cells.
When to use each
Use a spreadsheet if you…
- Need custom formulas and calculated fields specific to your workflow
- Want to share and collaborate with a partner or accountant
- Need full data portability (CSV, native everywhere)
- Enjoy building and maintaining your own system
- Need to track things beyond expenses (inventory, invoices, payroll)
Use Kachink if you…
- Value consistency over customization — you'd rather log 100% of expenses simply than 50% with complex formulas
- Already use Claude daily and want finances in the same window
- Handle multiple currencies and don't want to maintain GOOGLEFINANCE() lookups
- Want spending summaries without building pivot tables
- Need a system that works as well on mobile as desktop
It's not about features — it's about consistency
The best expense tracker is the one you actually use. Spreadsheets win on flexibility. Kachink wins on friction — or rather, the lack of it.
The abandoned spreadsheet
Most developers have a half-finished budget spreadsheet from January. It had beautiful charts. It lasted six weeks. The problem was never the tool — it was the 30-second tax on every transaction.
The one-line alternative
With Kachink, you type "$47 lunch" mid-conversation. No tab switching, no cell selection, no formula anxiety. That difference compounds over months.
The hybrid approach
Some people use Kachink for daily logging (zero friction) and export a monthly summary to a spreadsheet for custom analysis. Best of both worlds.
The fastest way to decide
Keep your spreadsheet. Add Kachink to Claude, log expenses for a week in both, and see which one you actually stick with.

Comparison questions
Yes. Ask Claude to export your data and you'll get a full JSON dump of all transactions. You can convert this to CSV or paste summaries directly into your spreadsheet.
No. Kachink tracks transactions, categorizes them, and provides summaries. If you need custom calculations, a spreadsheet is the better tool — or use both.
Yes, Kachink is free. You need a Claude.ai account (the free tier works). Google Sheets is also free, so cost isn't a differentiator here — workflow fit is.
There's no bulk import — you'd start fresh in Kachink. But since Kachink is designed for going-forward tracking (not historical analysis), this works well. Keep your old spreadsheet as an archive.
