Keeping a betting record: CSV, XLSX and export files
Most regular bettors have a rough idea of how they are doing. Very few have an accurate one. A simple record, kept in a spreadsheet or a plain text file, replaces memory with numbers, and the export tools many operators now provide make it easier than it used to be.
What operators let you download
Many licensed sportsbooks and casinos offer an account history page with a date filter and, increasingly, an export button. Exports are usually CSV files, sometimes XLSX or PDF. Regulations in some countries also require operators to show net deposit or win/loss figures over a period, which is a quick sanity check against your own numbers.
CSV, XLSX and PDF in short
| Format | What it is | Good for |
|---|---|---|
| CSV | Plain text, one row per line, values separated by commas or semicolons | Importing into any spreadsheet or script |
| XLSX | Excel workbook (zipped XML inside) | Keeping formulas, sheets and formatting |
| Fixed-layout document | Statements to keep, not to calculate with |
One CSV pitfall: in many European locales the comma is the decimal separator, so exports use semicolons between fields. If a CSV opens with everything in one column, use the spreadsheet's import function and choose the right separator.
A simple record layout
If you keep your own record, these columns cover almost everything:
- date and time;
- sport or game, and market;
- stake and odds (or game and bet size);
- result and profit or loss;
- a short note: why you placed it.
The note column is the most useful one after a few months: it shows which kinds of bets actually work for you and which were made on impulse.
File habits
Name files by date (for example 2026-10_bets.csv), keep one master workbook and back it up, just as you would any other personal records. Exports contain account details, so store them somewhere private rather than in a shared folder.
A record also makes budgeting concrete: once the numbers are in front of you, setting a monthly limit with the operator's own deposit-limit tool is a five-minute job.
