About — Statement Parser

A tool for converting Japanese property management PDF statements into structured CSV data.

What it does

Property management companies in Japan issue monthly settlement statements (月次精算書) as PDFs. These are detailed but not machine-readable — getting the numbers into a spreadsheet means manual data entry.

This tool reads those PDFs using AI and extracts the structured data automatically: room-by-room income, expense categories, and monthly totals. The output is clean CSV files you can open directly in Excel.

How it works

Upload PDFs

Drag and drop one or more monthly statement PDFs. Up to 15 at a time.

AI extraction

Each PDF is sent to an AI model (Google Gemini by default) which reads the statement and returns structured data — income per room, expenses by category, and the net transfer amount.

Review and download

Results appear immediately. Download individual monthly CSVs, or click "Download ZIP" to get all months plus an aggregated annual pivot in one file.
