Excel Template Structure

To process calculations accurately, the parser expects source and destination pincode mappings in specific columns. Make sure your spreadsheet matches these structural rules:

Column Index Mapping

  • Column B: Source Pincode (6 digits)
  • Column D: Destination Pincode (6 digits)
  • Column E: Populated results cell

File Constraints

  • Formats: Excel Sheets (.xlsx, .xls)
  • Size limit: Maximum 10MB uploads
  • Headers: Row 1 is reserved for table headers

Step-by-Step Preparation Guide

1

Create the Spreadsheet Table

Open Excel or Google Sheets, define standard column titles in the first row, and ensure Columns B and D contain the 6-digit postal codes to compute.

2

Verify Pincode Format

Ensure all postal codes are valid 6-digit numeric strings. Leading zeroes should be preserved by formatting the column cells as 'Text'.

3

Save & Upload

Save the worksheet locally as `.xlsx` or `.xls` format (must be under 10MB), and upload it inside the calculator's file picker box above.

4

Download Calculated File

Click 'Upload & Calculate'. Once processed, review results on the next page and click 'Download results' to download your completed sheet with calculated distances in Column E.

Frequently Asked Questions

Calculated distances are output in Kilometers (km) by default. The distance is calculated as great-circle distance (Haversine formula) using high-precision latitude/longitude GPS markers.
The bulk calculator currently processes `.xlsx` and `.xls` files. Standard CSV files can be opened in Excel and easily resaved as Excel files before uploading.
The calculator will skip rows with missing codes and record 'Not found' in the output results for those specific rows, allowing the rest of the spreadsheet to process without throwing errors.
