What Is a TSV Analyzer?

This online tool analyzes Tab Separated Values (TSV) data. It checks the structure of a TSV file, identifies the kinds of values stored in its cells, and can also run detailed analysis for specific columns. This is useful when you receive a TSV export and want to quickly check whether it is safe to import into a spreadsheet, or when a script does not parse a TSV file as expected, and you need to find missing fields, blank values, or inconsistent columns. The input should be TSV data with tab characters between cells. Before the analysis runs, the tool can clean up the input by skipping comment rows and blank rows. Comment rows are identified by a marker that you choose, such as "#". Any row that starts with this marker can be excluded from the statistics. The first row can be treated as a header row. When this option is enabled, the top row is used as column labels and stays available for selecting columns by name. At the same time, it is not counted as data, so its cells are excluded from value totals, type detection, and length measurements. When the option is disabled, the first row is treated as a regular data row and included in the analysis. The options let you choose which information blocks to show in the report. The TSV structure block shows the overall shape of the table, including row count, column count, expected cell count, actual cell count, and the locations of empty, whitespace-only, and missing cells. The value type block shows what kinds of data appear in the table, such as strings, integers, decimals, booleans, dates, times, date-time values, email addresses, and URLs. The value length block finds the shortest and longest filled TSV cells and shows their exact locations in the table. You can also print detailed information about selected columns. Columns can be selected by position, by ranges such as 2-4, by negative positions such as -1 for the last column, or by header text. If a header appears in multiple columns, you can keep only the first match or include every matching column. Each column section shows the first column value, existing, empty, whitespace-only, and missing counts, the dominant value type, numeric minimum, maximum, and average when numbers are present, plus the shortest and longest value in that column. Tsv-abulous!

Inspect an Origami Fold TSV

In this example, we inspect a small TSV sheet for origami models. The table has one header row and three complete data rows with fold names, step counts, and difficulty levels. The first row is used only as headers, so its cells are not included in row counts, cell totals, empty checks, or missing-value checks. The report describes the data area below the header: 3 rows, 3 TSV columns, and 9 filled data cells.

fold steps level crane 18 hard boat 10 easy star 12 med
General Information: -------------------- Rows: 3 (excluding header row) Columns: 3 Expected values: 9 (3 rows × 3 columns) Total values: 9 (including empty and whitespace-only values) Empty values: 0 (zero-length values and whitespace-only values) Whitespace-only values: 0 Missing values: 0

Analyze Radio Contact TSV Values

In this example, we analyze a compact amateur radio contact TSV. The table has four columns: call, time, confirmed, and ref. Since the header row is included in the analysis, the header values are counted together with the contact records and appear in the value length results. The analyzer skips the comment row, finds one missing ref value in the last contact, and detects a mix of TSV value types: strings, times, booleans, emails, and one URL. It also reports the shortest and longest filled cells with their exact row and column positions.

call time confirmed ref K7HAM 21:30 true k7@qsl.fm M0QSL 06:15 false https://mqs.radio JA1DX 11:24 true ja@qsl.jp LU5AR 23:05 false # duplicate contact
General Information: -------------------- Rows: 5 (including header row) Columns: 4 Expected values: 20 (5 rows × 4 columns) Total values: 19 (including empty and whitespace-only values) Empty values: 0 (zero-length values and whitespace-only values) Whitespace-only values: 0 Missing values: 1 • row 5, column 4 Value Types: ------------ String values: 15 Numeric values: 0 • Integer values: 0 • Decimal values: 0 Boolean values: 4 (values: true, false) Date values: 0 Time values: 4 (format: HH:MM) Date and time values: 0 Email values: 2 (format: *@*.*) URL values: 1 (format: https://*) Value Lengths: -------------- Shortest non-empty values: • "ref" — 3 characters, row 1, column 4 • "call" — 4 characters, row 1, column 1 • "time" — 4 characters, row 1, column 2 • "true" — 4 characters, row 2, column 3 • "true" — 4 characters, row 4, column 3 Longest non-empty values: • "https://mqs.radio" — 17 characters, row 3, column 4 • "confirmed" — 9 characters, row 1, column 3 • "k7@qsl.fm" — 9 characters, row 2, column 4 • "ja@qsl.jp" — 9 characters, row 4, column 4 • "K7HAM" — 5 characters, row 2, column 1

Review Shadow Theater Columns

In this example, we review every column in a TSV cue sheet for a shadow theater show. Column analysis is enabled for positions 1-4, so each column gets its own detailed report. The "cue" column contains short string IDs, the "scene" column contains text labels with different lengths, the "level" column contains integers with a minimum, maximum, and average value, and the "ready" column contains boolean true/false values. The report also confirms that every column is complete, with no empty, whitespace-only, or missing values.

cue scene level ready C01 Gate 20 true C02 Lantern 35 true C03 Storm 55 false C04 Curtain 30 true
Column #1: ---------- First value: "cue" Total values: 4 Empty values: 0 Whitespace-only values: 0 Missing values: 0 Values type: string Shortest value: "C01" — 3 characters Longest value: "C01" — 3 characters Column #2: ---------- First value: "scene" Total values: 4 Empty values: 0 Whitespace-only values: 0 Missing values: 0 Values type: string Shortest value: "Gate" — 4 characters Longest value: "Lantern" — 7 characters Column #3: ---------- First value: "level" Total values: 4 Empty values: 0 Whitespace-only values: 0 Missing values: 0 Values type: integer Integer values: 4 Minimum number: 20 Maximum number: 55 Average number: 35 Shortest value: "20" — 2 characters Longest value: "20" — 2 characters Column #4: ---------- First value: "ready" Total values: 4 Empty values: 0 Whitespace-only values: 0 Missing values: 0 Values type: boolean Boolean values: 4 (values: true, false) Shortest value: "true" — 4 characters Longest value: "false" — 5 characters
