All free flowsMQTT Subscription Gap Review TSV
Compare one local topic filter with ordered topic names, then download only unmatched occurrences as a protected TSV follow-up queue.
Processing stays in your browser; code and assets download as needed. Original and checkpoint downloads retain source content, including omitted values. Reset and Exit stop this session’s owned work; they do not establish secure erasure or anonymity. Matching is offline; no broker is contacted.

About this flow
Find topic occurrences outside one local MQTT filter and prepare an ordered, protected TSV follow-up queue, retaining duplicates and exact matching rules.
Limitations
- One strict UTF-8 TXT file or pasted topic list. Filter plus topic-list source must fit 1 MiB UTF-8; each filter/topic is 1–65,535 UTF-8 bytes and at most 65,535 UTF-16 units. 1–10,000 nonempty topics in source order; CRLF, CR or LF separate lines and one terminal terminator is allowed. Empty slash levels are valid, internal empty topic lines are not. No trimming, Unicode normalization or BOM stripping. Controls, Unicode noncharacters, shared subscriptions and wildcard topic names reject. Original worker: 30 seconds and 5 MiB complete JSON; each next JSON/CSV input 5 MiB; JSON 200,000 values/40 levels; converter 10,000 records/200 columns/200,000 data cells. Final TSV <=20 MiB. Protected CSV/TSV prefixes some formula-like text with an apostrophe under maintained writers; the raw original JSON keeps literal topic strings. Not a byte-exact broker configuration, numeric/type import or universal spreadsheet-security guarantee. All-matched input yields topic header only. Final success retains original topic input and latest selected CSV checkpoint, not the full matcher report.
