Recovering and Reusing Legacy XML / JSON Across Years of Content

Several clients came with large volumes of legacy content built up over many years:

  • Inconsistent XML or JSON structures

  • Partial translations

  • Files no longer compatible with modern TMS setups

In some cases, this content was still actively referenced or updated.

What I did

I reverse-engineered file structures and built tooling to recover and realign legacy content so it could be reused safely.

This typically involved:

  • Analysing and reconstructing schemas

  • Programmatically aligning source and target content

  • Recovering usable translations from historical data

  • Producing validated, future-proof outputs

Scale & longevity

  • Content spanning many years

  • Tens of thousands of segments

  • Multiple languages and formats

The outcome

  • Legacy content became usable again

  • Clients avoided large-scale retranslation

  • Older content could now be maintained alongside new material

This work turned long-term technical debt into usable assets.
