Lorebook Converter

JanitorAI lorebook txt/JSON → SillyTavern World Info JSON

Like this tool? Consider supporting me

This tool works ONLY on JanitorAI lorebooks NOT advanced scripts. Upload your JanitorAI lorebook information to the 'Source' and press 'Convert'. The output should be ready to import into ST. Anything the source doesn't give a rule for is preserved under extensions.janitorai_source. Everything below "Advanced settings" is adjustable. Remember to always double check the output and make your own adjustments.

Output SillyTavern World Info JSON

Advanced settings

Ordering

Order base

Order step per priority rank

order = orderBase − (priority − 1) × orderStep, using each entry's priority field (falling back to insertion_order, then its position in the file). Lower JanitorAI priority number = higher SillyTavern order.

Placement

Position (used when source has none)

Default @Depth (used when source has none)

Role (for @Depth entries)

Recursion & matching

preventRecursion

caseSensitive / matchWholeWords

Treat depth-1 entries as transient (skip description/persona match, exclude recursion) — this tool's own conversion policy (inferred from one verified example), not a SillyTavern rule excludeRecursion (baseline, non-transient entries) delayUntilRecursion

Match sources (baseline — overridden to false by the depth-1 rule above when it applies)

Preservation

Preserve unmapped source fields in extensions.janitorai_source Preserve existing settings — for entries that already have a value (placement, recursion, match toggles, order, probability, etc. — including values tucked inside extensions/extensions.janitorai_source from a prior conversion), keep it. The Advanced settings above only fill in values that are missing.

How fields are mapped

SillyTavern field	Rule
`key` / `keysecondary`	from `key`/`keys` and `keysecondary`/`secondary_keys`. Regex-style strings (`/pattern/flags`) pass through untouched.
`comment`	from `comment`, falling back to `name` when empty.
`constant` / `vectorized`	`constant`, or true when `activationMode` is `"constant"`/`"vectorized"`.
`order`	formula above, from `priority`. Expect that you may need to hand-tune afterward.
`position` / `depth` / `role`	from the source when present, else the Advanced settings above (verified defaults: position 4, depth 3, role 0).
`disable` / `enabled`	`enabled: false` in the source → `disable: true`; both fields written.
`preventRecursion`	Auto mode (this tool's heuristic, not a SillyTavern rule): true when `tags` includes `"world"`
`group`	from `inclusionGroupRaw`, falling back to `group`, else empty.
`delay`	from `minMessages` when > 0, else 0.
`probability` / `groupWeight`	copied directly, default 100.
`caseSensitive` / `matchWholeWords`	null by default — the reference book had these null even where the source set `matchWholeWords: true`. Switchable to pass-through above.
match* fields	from the checkboxes above; the depth-1 rule above (this tool's own policy, not something SillyTavern requires) can override description/persona to false and force `excludeRecursion` true for that entry.
`extensions`	mirrors `{position, role, depth, sticky, cooldown, delay}` (matches the reference book's legacy-compat duplication), plus unmapped source fields under `extensions.janitorai_source` when preservation is on.
"Preserve existing settings"	when on, any field the entry already has a value for — at the top level, under `extensions`, or nested in `extensions.janitorai_source` from an earlier conversion — is kept as-is, including `order`. Advanced settings above are only used to fill in what's actually missing. Turn it off to force every entry to the Advanced settings values instead.
