How to Fix a Spreadsheet-to-Game Import Losing Leading Zeros and Types

Your item id 0042 imports as 42 and a long numeric code becomes 1.23E+11. The spreadsheet helpfully reinterpreted text as numbers. Lock the column types and keep ids as strings end to end.

How to fix it

1. Format id columns as text

In the source sheet, set id and code columns to plain-text formatting so the editor stops stripping leading zeros and reformatting long numbers.

2. Quote on export

Export with fields quoted so the importer receives "0042" verbatim instead of a number the sheet already collapsed.

3. Parse ids as strings

In your importer, read id fields as strings, never as ints, so no numeric reinterpretation can happen on your side either.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.
