Flatten — Data Flattening Reference

Quick-reference skill for flattening nested data structures into flat key-value pairs or single-level arrays.

When to Use

• Converting deeply nested JSON into flat dot-notation objects
• Flattening multi-dimensional arrays into single-level lists
• Normalizing hierarchical API responses for tabular storage
• Preparing nested data for CSV export or database insertion
• Controlling flatten depth for partial flattening

Commands

intro

scripts/script.sh intro

Overview of data flattening — what it means, why it matters, core concepts.

json

scripts/script.sh json

JSON object flattening — dot-notation keys, bracket notation, separator options.

array

scripts/script.sh array

Array flattening — multi-dimensional to single-level, depth-limited flatten.

algorithms

scripts/script.sh algorithms

Flattening algorithms — recursive vs iterative, stack-based, BFS approaches.

languages

scripts/script.sh languages

Flatten implementations across languages — JavaScript, Python, Go, Bash, SQL.

edgecases

scripts/script.sh edgecases

Edge cases — circular references, null values, mixed types, empty containers.

unflatten

scripts/script.sh unflatten

Reverse operation — reconstructing nested structures from flat key-value pairs.

patterns

scripts/script.sh patterns

Real-world patterns — ETL pipelines, log normalization, config merging.
