How to Generate a Continuous VLOOKUP Column Index with SEQUENCE in Excel

Maira Mehtab Sep 22, 2026 868 views

Question details

The user needs a method to pull a massive amount of contiguous columns (e.g., 1000 columns of biodata) from one sheet to another using VLOOKUP without manually typing out every single column index number.

Product: Excel
Device & OS: not provided
Scenario: Mapping a very large number of contiguous columns across different worksheets to consolidate biodata records.
Observed behavior: Manually typing an array of hundreds of column index numbers (like {2, 3, 4...1000}) in the VLOOKUP formula is tedious and impractical, prompting the need for an automated numerical array generator.

Before you start

Ensure you are using a spreadsheet version that supports Dynamic Arrays (such as Excel 365, Excel 2021, or the latest version of WPS Office) to utilize the SEQUENCE function properly.

Solution 1Recommended

Use SEQUENCE inside the VLOOKUP Column Index

By nesting the SEQUENCE function directly within VLOOKUP's column index parameter, you can automatically generate an array of numbers representing your contiguous columns.

The SEQUENCE function can generate a continuous array of numbers (e.g., 1 to 1000) dynamically. When placed inside the VLOOKUP formula as the third parameter, it tells the formula to return multiple contiguous columns simultaneously.

Select your destination cell

Click on the cell where you want the first column of the mapped data to appear.

Start the VLOOKUP formula

Type `=VLOOKUP(` and select your lookup value (e.g., the ID of the biodata row), then select your entire table array in the source sheet.

Insert the SEQUENCE function

For the column_index_num parameter, type `SEQUENCE(1, 1000, start_column, 1)`. Replace '1000' with the exact number of columns you need to retrieve, and 'start_column' with the first index number you want to pull (for example, 2).

Complete the formula

Add `, FALSE)` for an exact match, close the parenthesis, and press Enter. The results will automatically spill across the subsequent columns.

Dynamic Spilling: Ensure that the cells to the right of your formula are completely empty so the 1000 columns can spill out without causing a #SPILL! error.

Solution 2

Use XLOOKUP for Massive Contiguous Mappings

For mapping a large number of contiguous columns, XLOOKUP provides a more robust and cleaner syntax than VLOOKUP by completely avoiding index numbers.

Efficient Spreadsheet Data Mapping

Handle Massive Datasets Seamlessly with WPS Spreadsheet

WPS Office Spreadsheet fully supports advanced dynamic array functions, allowing you to use complex VLOOKUP, XLOOKUP, and SEQUENCE combinations to pull thousands of columns with a single keystroke.

1. Open your workbook: Launch WPS Spreadsheet and open the workbook containing your biodata sheets.
2. Enter your dynamic formula: In the target cell, type `=VLOOKUP(A2, Sheet1!A:ALL, SEQUENCE(1, 1000, 2, 1), FALSE)`.
3. Press Enter to execute: Hit Enter, and WPS Spreadsheet will instantly calculate and spill all 1000 mapped columns into your current worksheet.

Frequently Asked Questions

Why does my SEQUENCE function return a #NAME? error?

This error typically occurs if you are using an older version of Excel (like Excel 2016 or 2019) that does not support the SEQUENCE function. You need a modern spreadsheet software that supports dynamic arrays, such as Excel 365, Excel 2021, or WPS Office.

Can I use SEQUENCE if the columns I want to return are not continuous?

No, SEQUENCE only generates a continuous mathematical series (e.g., 2, 3, 4, 5). If you need non-contiguous columns (e.g., columns 2, 5, and 9), you must manually type the array like {2,5,9} or use the CHOOSECOLS function instead.

Why is my VLOOKUP returning a #SPILL! error?

A #SPILL! error means the dynamic array formula is attempting to output data into adjacent cells, but those cells already contain data, text, or even hidden spaces. Clear all data in the destination columns to allow the sequence to expand properly.

Is XLOOKUP better than VLOOKUP for thousands of columns?

Yes, XLOOKUP is highly recommended for massive column returns because it allows you to directly reference the return array (e.g., columns B through ZZ) rather than relying on counted column index numbers, making it faster and easier to maintain.
