Vendor Format Converter for IDT, Twist, GenScript and Dynegene

Convert FASTA, CSV, or plain text sequences to vendor-specific order formats for IDT oPools,Twist Bioscience, GenScript, and Dynegene. Validate sequence characters, calculate GC content, and export Excel/CSV files for vendor portal review.

Vendor-specific order file workspace

Use this after: sequences pass Batch QC and the vendor or quote path is already chosen.

Example input: FASTA or CSV names and sequences; output becomes an IDT, Twist, GenScript, or Dynegene-style order file.

Not for: generic FASTA/CSV/TSV cleanup. Use Format Converter before this page when the vendor is not selected yet.

Why You Need a Vendor Format Adapter

Each oligonucleotide synthesis vendor has its own proprietary ordering format — different column names, required fields, scale options, purification codes, and file formats. Converting your sequences from a universal format (FASTA, CSV) into vendor-specific order files is tedious and error-prone when done manually, especially for large oligo pools with thousands of sequences.

The Vendor Format Adapter supports IDT, Twist Bioscience, GenScript, and Dynegene-style export templates. It generates Excel/CSV files with the column structure, sequence names, length fields, GC% values, and selected order options needed for vendor portal review.

Use this vendor order-format page when you need to convert sequences into vendor-specific order files; use the vendor directory, comparison, and ordering guide pages when you still need provider discovery, vendor selection, or submission context.

Use this after sequences pass Batch QC and the vendor or quote path is already chosen. Example input: FASTA or CSV names and sequences; output becomes an IDT, Twist, GenScript, or Dynegene-style order file. Use the generic Format Converter first when you only need FASTA, CSV, or TSV cleanup and the vendor is not selected yet.

If you searched for CSV to FASTA, FASTA converter, or FASTA to CSV, start with Format Converter before vendor-specific export.

Use the adapter as a pre-submission formatting and review step, not as the final source of vendor capability truth. It flags sequence length, unsupported characters, and GC content concerns so you know what to verify in the current vendor portal, quote, or public product page before ordering.

How to Use the Vendor Format Adapter

  1. Upload your sequences: paste from clipboard, upload a FASTA/CSV file, or paste tab-separated name-sequence pairs.
  2. Select the target export template: IDT, Twist Bioscience, GenScript, or Dynegene.
  3. Configure order options: synthesis scale (25 nmol, 100 nmol, etc.), purification method (Desalting, HPLC, PAGE), and naming scheme.
  4. Review validation results: sequences with length, character, GC%, or formatting concerns are flagged for manual review.
  5. Download the formatted Excel or CSV file, then confirm the current vendor portal requirements before submission.

Frequently Asked Questions

What format does IDT require for oligo pool orders?
The IDT export template uses order-file fields such as pool or oligo name, sequence, scale, purification, and optional notes depending on the selected mode. Treat the exported file as a clean starting point: verify the current IDT portal columns, product tier, sequence-length window, and modification rules before submitting an order.
What are the sequence length limits for each vendor?
The adapter flags unusually short or long sequences so they can be reviewed before upload. Current limits depend on vendor, product tier, modification status, and quote terms, so confirm the final length window on the vendor portal or current product documentation before ordering.
How do I choose between vendors for my oligo pool?
Use this page after you have selected a vendor format. For vendor choice, compare pool size, sequence length, QC scope, delivery amount, turnaround, and quote terms on the oligo pool vendor comparison page, then confirm the current product documentation before submitting files.
Can I include modifications in my vendor order?
You can include modification fields in export templates that support them, but modification availability depends on the vendor, product tier, sequence length, scale, and quote. Keep modifications explicit in the file and verify compatibility directly before ordering.
What happens if my sequence contains invalid characters?
Our adapter validates all sequences against the target vendor's accepted alphabet. Most vendors accept standard DNA bases (A, T, C, G) and some accept IUPAC ambiguity codes (R, Y, S, W, etc.) depending on the product type. Sequences containing invalid characters (numbers, spaces, non-IUPAC letters) are flagged with specific error messages. You can fix these in the tool before downloading the order file, preventing submission errors and order delays.
