ChatGPT vs Claude for month-end bank reconciliation
Quick answer
Either one can do the matching step of a bank reconciliation: upload the bank statement and the ledger export as CSV files, give the opening and ending balances, and ask for every row that does not match, with a reason. ChatGPT is the one Stepthrough has tested end to end on this job. Claude also analyzes uploaded CSV files by running code, according to Anthropic. The tool matters less than three habits: give it the balances, add the exceptions up yourself, and keep client data on an approved business plan.

How do they compare at a glance?
| Question | ChatGPT | Claude |
|---|---|---|
| Can you upload both CSV files? | Yes. The lesson uploads a bank statement and a ledger export. | Yes. Anthropic says you can upload CSV and similar files for analysis. |
| How does it do the matching? | Often by writing and running code on your file, which you can open and read. | By running code in its code execution feature, which Anthropic lists for Free, Pro, Max, Team and Enterprise plans. |
| Tested by Stepthrough on this job? | Yes, in a real account: 38 of 40 rows matched on each side and the four planted exceptions were listed. | Not yet. No result is claimed. |

| What you must still do | Add the exceptions up and check the two adjusted balances agree. | The same: add the exceptions up and check the two adjusted balances agree. |
Which is better at bank reconciliation, ChatGPT or Claude?
We can't honestly say. Both are general AI assistants that can read an uploaded spreadsheet file and run code on it, and the result depends far more on your prompt and your files than on the logo. What we can say is what has been tested: in the ChatGPT lesson, ChatGPT matched 38 of 40 rows on each side of a made-up studio's September, listed exactly the four planted exceptions, and produced a summary table that added up.
If you already pay for one of them on a business plan, use that one. Switching tools for this job is rarely worth it. If you want to compare, run your own test: give both the same two files and the same prompt, then check each answer against the rows. For the broader picture, see ChatGPT vs Claude.
What do you give the AI to reconcile a bank statement?
Two CSV exports, the bank statement and the ledger, plus the opening balance and both ending balances. The balances matter most: with them, the assistant can show that its list of exceptions explains the gap, and you can see when it has missed something. In the lesson's example the gap is $4,370.50, and the four exceptions add up to exactly that.
Ask it to match by amount and date within a few days, to list every unmatched row with a likely reason, and to say "Needs review" instead of guessing. The bank reconciliation glossary page explains the terms.
Can you trust the totals AI gives you?
Trust, but add them up yourself. AI can add wrong, and a reconciliation that is off by a few dollars looks finished while it isn't. The lesson makes you do the arithmetic with a calculator: the adjusted bank balance and the adjusted book balance should land on the same number. If they don't, ask for the rows behind each total, or open the code it ran, and look for a row it skipped.
This applies equally to ChatGPT and Claude. Neither replaces your judgment on each exception, recording the entries in your accounting software, or your sign-off.
Is it safe to upload a bank statement to ChatGPT or Claude?
Only on an account your firm has approved, and only after you remove what the matching doesn't need, such as account numbers. Business plans are the usual choice for client work because vendors say they do not train on business data by default, but confirm the terms of your exact plan. Personal accounts are a different matter and have settings you must check yourself.

Who is each one for?
ChatGPT
A good fit if you want to practice the exact routine first. Month-End Bank Reconciliation with ChatGPT uses sample CSV files you can also upload to a real account.
Claude
A reasonable choice if your firm already uses it. Anthropic lists CSV analysis and code execution on all plans. Treat the same checks as non-negotiable, and run your own comparison on a past month before you rely on it.

Key takeaways
- Both can match two CSV files and list exceptions; only ChatGPT has been tested end to end by Stepthrough on this job.
- Always give the opening and ending balances so the assistant can prove its list explains the gap.
- Add the exceptions up yourself and confirm both adjusted balances agree before you sign off.
- Use an approved business plan and remove account numbers before you upload.
Frequently asked questions
Can Claude reconcile a bank statement?
Claude can analyze uploaded CSV files by running code, so it can match a bank file to a ledger file. Give it the balances, ask for unmatched rows with reasons, and check the totals yourself.
Which is more accurate for bookkeeping, ChatGPT or Claude?
We haven't run a head-to-head test, so we don't claim one is. Test both on a month you have already closed and compare the exceptions to your own.
Does AI replace QuickBooks or Xero bank feeds?
No. Bank feeds and rules in your accounting software match many transactions and are where entries get recorded. AI helps most with a messy month that doesn't tie.
What should I remove before uploading a bank statement?
Account numbers and anything the matching doesn't need, and follow your firm's AI policy first.
