Bank statement PDF to Excel in Singapore: the options compared

Manual entry, generic PDF converters, AI chatbots, or a bank-specific converter: what each costs, what breaks, and how to check the result.

Every bookkeeper in Singapore meets the same problem each month: a stack of PDF statements from UOB, DBS, POSB and OCBC that need to become rows in a spreadsheet or an accounting system. Here are the four ways people do it, and what goes wrong with each.

1. Type it in

Reliable, slow, and the way most small businesses still do it. A 100-transaction statement takes 30 to 60 minutes and the errors are the quiet kind: a transposed digit, a line skipped. The only check is the closing balance, and if it's off you hunt.

2. Generic PDF-to-Excel converters

These read any PDF as a table. On bank statements they split multi-line descriptions into separate rows, mash withdrawals and deposits into one column when the bank leaves one blank, and hand you a sheet that needs ten minutes of clean-up. Most charge a monthly subscription whether you use it or not.

3. AI chatbots

Paste the PDF, ask for a table. Usually close; sometimes an amount is wrong and nothing tells you. Many services keep uploaded files, which is a problem for a document with your name, address and account number on it.

4. A converter built for these banks

One parser per bank layout, so UOB's foreign-currency lines, OCBC's value dates and DBS's consolidated statements each come out right. The important difference is the check: the running balance is recomputed from the opening figure and compared to the bank's printed balance on every row. A row that doesn't reconcile is flagged.

How to check any conversion, whichever method you use

  1. Opening balance plus total deposits minus total withdrawals must equal the closing balance.
  2. Count the rows against the number of transactions on the PDF.
  3. Spot-check three multi-line entries: the description should be complete and the amount on the right line.

StatementSheet does these checks automatically. The first statement each month is free, so you can compare it against your current method on a real file.
