Optional: Check Your Work Packs (Ch01–Ch04)

This workbook is meant to be a learning experience, not a “gotcha” test. If you want to confirm you’re on the right track (or you’re stuck), use the downloads below to compare your work against a known-good reference.

What these packs are for

Option A — “Check my spreadsheet work.” Download the completed XLSX for your chapter and compare the numbers you calculated (then export your CSVs again).
Option B — “Check my LedgerLoom run.” Run ledgerloom build and compare your generated artifacts to the reference outputs ZIP.

Canonical dataset contract

Each Workbook chapter has a canonical dataset under:

examples/workbook/<chapter_slug>/

Treat that folder as the “answer key”. The reference outputs ZIPs are generated by running:

ledgerloom build --run-id r1

for the canonical project and then zipping:

the exported input CSVs (what students should export)
outputs/r1/artifacts (what LedgerLoom should produce)
outputs/r1/trust (run metadata + manifest)

How to compare (recommended)

Build your run:

ledgerloom check --project path/to/your_project
ledgerloom build --project path/to/your_project --run-id myrun

Compare inputs first:
- inputs/<period>/transactions.csv
- inputs/<period>/adjustments.csv (blank in Ch01–Ch02)
Compare artifacts second:
- your outputs/myrun/artifacts/*.csv
- the reference ZIP’s artifacts/*.csv

If your results differ, it’s almost always one of these: a swapped debit/credit, a wrong account root, a missing line inside an entry_id, or an adjustment that belongs to a different period.

See Workbook Troubleshooting for quick fixes.

Workbook Ch01 — Startup (solution pack)

Canonical dataset:

examples/workbook/ch01_startup

Downloads

What the reference outputs include

entries.csv (the canonical journal lines)
trial_balance_unadjusted.csv

Workbook Ch02 — Journal → Trial Balance (solution pack)

Canonical dataset:

examples/workbook/ch02_journal_to_trial_balance

Downloads

What the reference outputs include

entries.csv
trial_balance_unadjusted.csv

Workbook Ch03 — Adjusting entries (solution pack)

Canonical dataset:

examples/workbook/ch03_adjusting_entries

Downloads

What the reference outputs include

entries.csv
trial_balance_unadjusted.csv
trial_balance_adjusted.csv

Workbook Ch04 — Closing + post-close TB (solution pack)

Canonical dataset:

examples/workbook/ch04_closing_and_post_close

Downloads

What the reference outputs include

entries.csv
trial_balance_adjusted.csv
closing_entries.csv
trial_balance_post_close.csv

Post-close invariant: the post-close trial balance must contain only balance-sheet accounts (Assets / Liabilities / Equity). Revenue and Expense accounts should be zeroed out.
