Three steps. Zero scripting.

From upload to download in under a minute, with the schema doing the validation work for you.

1

Upload your Excel

Drop in any .xlsx, .xls, or .csv. We parse headers and rows on the server — your file never leaves your account.

2

Map columns to fields

We auto-propose matches based on column names. Drag, drop, set defaults, save the mapping as a reusable template.

3

Download valid XML

Conversion runs in the background, validates against the target XSD, and gives you a downloadable file with a green tick.

Bring any schema you need

Upload the XSD you're working with — auto-detected, editable, and reusable for every future run.

E-commerce

E-commerce product feeds

Ship inventory to Skroutz, BestPrice, or any marketplace that asks for XML. Required-field validation built in.

Accounting

Accounting & tax filings

Convert ledger or invoice exports into schemas like myDATA or partner-specific XML. Upload the schema, we handle the wiring.

B2B / EDI

B2B / EDI exchanges

Bring the partner XSD you were sent, map columns once, save the template, run again next cycle.

Simple schemas, complex schemas — same tool

Most XML converters give up as soon as the XSD stops being flat. NicheXML walks the schema, finds the branches, and lets you compose the output from several Excel sheets in a single run.

Simple XSDs

Flat product feeds, invoice line items, ledger exports. One sheet, one mapping, done. Takes under a minute.

  • ✓Auto-matched columns
  • ✓Required-field warnings
  • ✓Mapping templates for reuse
New

Complex XSDs

Deep nesting, xs:choice branches, Excel workbooks with a different sheet per record type — EU reporting schemas, tax filings, partner-specific EDI, whatever the schema throws at you.

  • ✓Nested paths detected automatically
  • ✓Multiple Excel sheets → one XML
  • ✓Fixed-value defaults for XSD code markers
  • ✓One upload = one conversion, regardless of sheet count

Why NicheXML

The features that turn a one-off spreadsheet conversion into a repeatable, reliable workflow.

XSD validation built-in

Every output is validated against the target schema. No more "the XML imported but the data is wrong" surprises.

Reusable mapping templates

Queue-backed at scale

Big files run on a background worker so the UI stays responsive even on 50k-row spreadsheets.
