Best TSV to JSON

Convert tab-separated values into clean JSON arrays with one click

JSON will appear here...
Splits on tabs and newlines, and unescapes \t, \n, \\ sequences within cells (the standard IANA text/tab-separated-values convention) — matching what you get pasting straight out of Excel or Google Sheets. Strips a UTF-8 BOM if present, and normalizes CRLF/CR/LF line endings. Output is built with JSON.stringify, so quotes, backslashes, and any JSON-looking text inside a cell are always escaped into valid JSON automatically — they stay as plain strings, never get re-parsed.

Type conversion rules (deterministic, no per-column exceptions): true / false convert to booleans only as exact lowercase — TRUE, False, etc. stay strings. null/NULL (any case) converts to JSON null — this one is intentionally case-insensitive, unlike booleans. Plain integers and decimals (e.g. 42, -3.5) convert to numbers, except: values with a leading zero before more digits (007, 0000123) stay strings, since a real number can't have one; integers that would lose precision as a 64-bit float (beyond Number.MAX_SAFE_INTEGER, e.g. a 20-digit ID) stay strings so the digits are never silently altered; and a number so long it would overflow to Infinity stays a string too, since JSON.stringify would otherwise silently turn it into null. Scientific notation (1e3) stays a string unless you enable the checkbox above. Whitespace around a cell is trimmed only to detect its type — a value that isn't a recognized type is kept byte-for-byte as received.

Data-safety checks, always on: every data row's column count is checked against the header (or against row 1, if there's no header) — a mismatch is reported below with the row number and expected/actual counts, but the row is still converted, never dropped. A row with extra columns keeps them under synthetic col_N keys instead of discarding them. A blank or duplicate header is renamed (col_N / name_2) with a warning, so two columns can never silently overwrite each other in the output. Only a trailing run of fully blank lines is ignored — a blank line in the middle of your data is kept as a real row.

Convert Spreadsheet Data into JSON Without Manual Formatting

Spreadsheet data is easy to organize, but using it in applications or development projects often requires it to be in JSON format. Instead of creating JSON objects row by row, you can let our TSV to JSON online converter handle the work for you. Simply paste your tab-separated data, click Convert, and get a properly structured JSON array within seconds.

Whether you're exporting records from Excel, copying data from Google Sheets, or preparing information for an API, this tool helps you transform tabular data into clean JSON quickly and accurately. Since everything is processed in your browser, your data stays private from start to finish.

What is TSV to JSON?

TSV to JSON is a tool that converts Tab Separated Values (TSV) into a JSON array. It uses the first row as the header, treats each remaining row as a separate record, and creates a JSON object for every entry. The converter also recognizes values that look like numbers or booleans, so the output is properly formatted and ready to use in your projects.

Now that you know what the TSV to JSON converter does, let's see how you can convert your tab-separated data into JSON in just a few simple steps.

Tips to Get the Best Results From Our Tool

To get the best JSON output, make sure your TSV data is clean and properly arranged before converting it. These simple tips will help you avoid common mistakes:

  • Use the First Row as Column Names: The first row should contain your column names. The tool uses these names as keys in the JSON output. Make sure each column has a clear name.
  • Keep All Rows Complete: Each row should have the same number of values as the header row. Missing or extra values can make the JSON incorrect.
  • Use Tabs Between Values: This tool only works with tab-separated values (TSV). If you copy data from Excel or Google Sheets, the tabs are usually added automatically.
  • Check Your Numbers and True/False Values: The converter changes numbers into numeric values and true or false into Boolean values. Make sure these values are written correctly before converting.
  • Remove Empty Rows: Delete any empty rows before you convert your data. This helps create a clean JSON file.
  • Use Simple Column Names: Choose short and clear column names. This makes your JSON easier to read and understand.
  • Check the Output Before Copying: Take a quick look at the JSON output to make sure everything is correct before you copy and use it.
  • Try the Example First: If this is your first time using the tool, click Load Example to see how it works before adding your own data.

Common TSV to JSON Issues and Their Solutions

Sometimes you may face small problems while converting TSV data. Here are some common issues and easy solutions:

Column Names Are Missing

  • Problem: The JSON output does not show the correct keys.
  • Solution: Make sure the first row contains the column names. The tool uses these names for every JSON object.

Data Is in the Wrong Place

  • Problem: Some values appear under the wrong keys.
  • Solution: Check that every row has the same number of tab-separated values as the header row.

Numbers Stay as Text

  • Problem: Numbers are not converted correctly.
  • Solution: Make sure the values contain only numbers. Remove extra spaces or symbols if needed.

True or False Is Not Converted

  • Problem: The tool treats true or false as text.
  • Solution: Write true and false correctly without extra spaces or quotation marks.

The Output Looks Wrong

  • Problem: The JSON output is not formatted correctly.
  • Solution: Copy the data directly from Excel, Google Sheets, or another TSV file. Do not replace tabs with spaces.

Empty Values Appear

  • Problem: Some fields in the JSON are empty.
  • Solution: Check your TSV data for blank cells. Fill them if needed before converting.

Large Files Take More Time

  • Problem: A large TSV file takes longer to convert.
  • Solution: Wait a few moments for the conversion to finish. If the file is very large, divide it into smaller parts and convert them one by one.
