Keying in invoices, merging spreadsheets, reconciling numbers, rebuilding the same month-end report. Office Lab makes tools that run on your own computer, plus Excel workbooks, to take that repetitive part off your desk. You keep the part that needs experience and judgment. Built for accounting, admin and office teams in Vietnam.
01 · The problem
In an accounting or admin office, the hours rarely disappear into hard problems. They go into simple tasks that keep coming back:
Added up, many people lose hours a week to this. Done by hand, it is easy to slip a digit when you are tired, and in accounting a single wrong digit can mean combing through the whole sheet to find it.
02 · Tools
Each tool does one specific job, and its page says plainly what it can't do yet. More will be added over time.
| Code | Tool | What it solves | For | Status |
|---|---|---|---|---|
| OL-01 | InvoiceXtract | Reads a folder of Vietnamese VAT e-invoices (PDF and XML) into one Excel file, and lists separately the invoices that need a second look. | Accountants entering purchase invoices | In real use |
| OL-02 | This row is kept for the next tool. | |||
Besides the tools listed here, I build custom tools around a specific team's process. Those are tied to client data, so they aren't shown on this site. If there's a repetitive task you'd like to get rid of, tell me about it: how it's done today, where the data comes from, and how often it comes around.
03 · How I work
These tools touch your numbers, so they have to be trustworthy before they're fast. Every Office Lab tool follows the same four rules.
If a value isn't certain, it stays blank with a reason attached. It's never filled in just to complete the column. An empty cell is far easier to deal with than a wrong number nobody notices.
Output always keeps the items that need a human check in a separate list, each with a specific reason. You know exactly where to look instead of re-checking everything.
If the original record exists, use it. With e-invoices, the XML file is always trusted over the PDF. The PDF is only used as a cross-check.
A one-off job is usually faster by hand than writing a tool for it. The tasks that come back every week are the ones worth handing to a machine.
04 · Next
These are plans, not features that run today. Each tool's page will be updated when they ship.
05 · Results
Only work that has run on real data goes here, and only numbers that were actually measured. Clients are kept anonymous.
06 · About
Office Lab is a one-person project. I pick tasks that office workers have to repeat, build a tool for exactly that task, and say clearly which parts have been checked against real data and which haven't yet.
I write both the tools and the guides that come with them. Each tool's limits are listed on its own page, so you know before you start.
